Stripes!

Marcy Petrini

January, 2018

 

Warp stripes are a (relatively) easy way to add color and design to our weaving – and there are many ways to include stripes, from sequential to random, from one color to several, and from thin to gradation, where we start with a background color and a stripe of a different color and slowly the stripe color becomes background and the background becomes color stripes as in the scarf below:

 

 

I say that stripes are relatively easy to add because it is also easy to make mistakes; two tend to occur: one is when we reverse the order of the bouts of warp, the other is when we flip the top and bottom of a bout. Examples will make this clearer and help avoid errors in the future.

Let’s say that we have bouts of 4” for a 20” shawl. This is the color stripes layout we have made; the ground is black; the stripes are in sets of yellow (½”); orange (1”); red (1 ½”):

 


 Bout # 1 = 4”
 

 Bout # 2 = 4”
 

 Bout # 3 = 4”
 

 Bout # 4 = 4”
 

 Bout # 4 = 4”
 
  4” black
 1.0” black


0.5" yellow

1.0” orange

1.5” red
 
  4” black
0.5" yellow


 1.0” orange

1.5” red

 1.0” black


  4” black

 

It is easy to see that swapping bouts # 2 and # 4 with any other bout would cause disaster. Always number the bouts the same way and then place them on the loom in the same way and in order. For example, I always tag the number the beginning of the bout, close to the warping board, and then I place each bout starting at the left side as I face the back of the loom, so that each tag is on the left of the bout. We have to be paying close attention and it’s still possible to make a mistake.

And I have made that error! Fortunately it was before I wound the warp on the loom (I dress from the back to the front); I noticed the odd stripes when I was spreading the warp at the cross; all I could do was re-tie the bouts, remove them from the back rod, and put them back in the right order.

You can have all of the bouts in the correct order and still make a mistake if one (or more!) is flipped. For example, image bout # 2 above, lined up in the back of my loom:

 

||||||||||||||| ||||||| ||||||||||||||| |||||||||||||||||||||| 

 

But if I flip the bout, my order will be red, orange, yellow and black. Not good!

This flipping can be avoided by tying the cross at the warping board differently at the top and the bottom.

 

 

In the figure above, you see that the top of the cross was tied with a yellow handle, the bottom with two separate red ties.

On the loom, the lease sticks are added so that the handle (white in this case) is up, as shown below. This helps not only with keeping me from flipping the warp, but also from twisting it, where one lease stick has the top of the warp on top and the other the bottom of the warp on top.

 

 

These type of errors, too, require re-placing the bout in the correct order and orientation. It is better to avoid it.

 

How do we design stripes? The February blog is just around the corner….

What Did I Get Done This Year?

Marcy Petrini

December, 2017

 

I am writing this blog at the end of December – the December blog! – but I know that with the busy life during the holidays, it won’t be posted until after the first of the new year. There is a reason for the traditional January 7th Roc Day, when the women returned to their fiber chores after the holidays!

I hope you had a wonderful holiday season and Happy 2018!

I don’t like to make new year resolutions, but as the old year ends and the one is about to begin, I like to assess what I have accomplished this past year and what the future is likely to bring.

My favorite piece this year is the plaited twill silk shawl, shown in my April 2017 blog; when asked to represent HGA for the fall issue of Fiber Art Now, I chose it and I am thrilled that it appears in in the “Spotlight on Organization” section. This is what I said in response to the question “What do you love about HGA?”

The sense of community, the educational opportunities, and the link between past and future. I became involved with HGA when there was no internet and a few written sources; the weavers across the country became my community of mentors, always willing to help. It was a thrill to meet them in person at Convergences®, where I learned more from them and others. Now it’s my generation’s turn to be mentors to ensure the future of our crafts. Through the Fiber Trust and scholarships, HGA offers valuable resources to young and upcoming fiber artists.

While that was my favorite piece of 2017, there were other weaving, knitting, spinning (a pound of red silk took nearly one year), and braiding; of the weaving (17) and knitting (8) pieces that were finished, the range was scarves, shawls and soft sculptures for exhibits, samples for our guild study group, writing and teaching, and one or two for new challenges – new yarn, new project, etc.

One of my friends brought me back a painted warp for two scarves from a conference and the challenge was to find two wefts that would work. The warp is cotton and rayon, size 10/2; I tried black, but it was too dark, making the warp colors almost disappear; even though gold is one of the warp colors, when used in the weft, it was just too much. Finally I found that cinnabar (for the scarf on the left) and copper (on the right) worked well; both colors are in the warp.

 

Both wefts are 50% wool, 50% silk, perfect for cold evenings. Both scarves were woven with a twill from Davison called a shadow twill – not shadow weave. Looking at the drawdown, we can see why she calls it “shadow”, the little motifs formed by the warp are shadowed by the weft.

Note that the treadles tied with 4 & 3, and 1 & 2 are duplicates, but since I have six treadles on the four shaft loom, tying these twice makes the treadling more efficient.

For 2018, the challenge is Convergence®. Four classes, four monographs and already over 60 participants signed up! I wish you a happy, fiber-filled 2018 and I do hope to see you in Reno!

Color: History!! Chemistry!!!!

Marcy Petrini

October, 2017

 

Don’t get put off by the title!

In October, my husband Terry Dwyer and I visited the Indianapolis Museum of Art for a fabulous exhibit called The Chemistry of Color. My intent was to come home and write my blog about it. But as Terry and I talked, we realized that the exhibit had piqued our curiosity even more and raised more questions than answers.

Terry (whose chemistry knowledge is far superior then mine, even though I have an undergraduate degree in it) started looking for answers – and the more he looked, the more curious we became….

Until he decided that all of that wonderful information should go on his newly established web site.

Here is a direct link to the summary of the exhibit in Terry’s website.

He is also writing summaries of the 12 pigments showcased in the exhibit, there are 5 listed in various levels of completion. Two that are finished are  Prussian blue (a pigment that owes its existence to the Castle Frankenstein) and ocher (King Midas could almost certainly have turned everything he touched to a golden color).

Even if you aren’t interested in the chemistry, there are all sorts of historical facts that I find fascinating, in particular the incidents surrounding the discovery of that unmistakable blue.

Enjoy!

Jurying a Convergence® Exhibit

Marcy Petrini

November, 2017

 

I am so honored that the 2018 Convergence® committee asked me to be the juror for the Truckee River Yardage Exhibit. The committee asks the jurors of the various exhibits to give talks, which is a wonderful way for the juror to explain how and why s/he chose the pieces that were chosen and for the participants to understand the method that the particular juror used.

 

 

Not surprisingly, I have been on both sides of the process, and whenever I think about it, I am always reminded of what one of my mentors early in my weaving career admonished, as she was trying to convince me to submit to a juried exhibit: “there will be times that you won’t be accepted, of course, “ she said, “it happens to everyone; you will first think that the juror is an idiot, later you will think you are an idiot, and finally you will come to your senses and try to see what you can learn from the experience, because that is the real reason to participate.” So true!

 

 

There are two kinds of exhibits; the first is open entry; most guild shows are open to its membership, or perhaps even to others; a juror then chooses pieces for the awards. I have juried this kind of exhibit and, while they may seem easy to judge, there are some underlining comparisons that make it really heard: how do you compare an exquisite garment with a wonderful tapestry? Then there is the comparison among participants: one piece may have been submitted by someone who is a long time artist, perhaps she sells her work, or maybe he teaches workshops on the technique used in the show piece; another entry may have been made by someone who has just started the journey and is a first time participant. Clearly we wouldn’t expect the same level of expertise between these two groups, yet they are in the same exhibit, vying for the same awards.

 

 

The other kind of exhibit is when only pieces that have been chosen by the juror are shown; the Truckee River Yardage Exhibit is one of those. In this case I will be comparing “apples to apples”; I will choose entries from swatches and then select pieces for awards on site. But I will likely receive many more entries that I am allowed to choose, because of space constraints. That’s when subtle differences in craftsmanship may matter, or when the complexity of the cloth may add to the aesthetics, for example.

 

 

A few years back I was at the instructor exhibit at Convergence® (which is by invitation) where one of my colleagues showed me her exquisite piece; baffled, she told me that it had won an award at a previous exhibit and yet had not been accepted for one of the juried exhibit at that Convergence®. Was the juror an idiot? It’s tempting to think that, but actually there may have been other circumstances that prevented her piece from being selected, the most common of which is that there is a theme that the juror is to follow, or the juror may look for pieces that fit well together for an overall scope.

 

 

Which brings me to the theme of this exhibit: the Truckee River. I have heard complaints from people that HGA announces the exhibit themes too late. But these themes are broad. Look at the images in this blog: they are all of the Truckee River, which I have obtained from the web. A river may make you think of rippling blue water, but these images show just about every color and texture that you may want to use for yardage. Just give it the appropriate name: inspired by a season (“Winter on the Truckee”), or the time of day (“Sunset at the Truckee”); research the topic and use as much imagination in naming the piece that you did in producing it. Here is a link to the exhibit information: http://www.weavespindye.org/convergence-2018-yardage-exhibit.

I hope to see you in Reno!

Weaving with with Yarn from the Stash

Marcy Petrini

September, 2017

 

The shawl I talked about last month was woven at the end of 2015. I had bought all of the Angora yarn that I had been able to find a few months earlier. I had used up 21 balls; the remaining 14 balls went to the “white” shelf – my yarn is stored in open shelves by color; the Angora wasn’t really white, but close enough for the purpose of storage. I periodically would have to move it out of the way to get to some other yarn, and every time, I would think: “this yarn feels so wonderful, I really should do something with it.”

In the middle of this year, I decided I would take my advice. Now I had to figure out what I could do with what I had since I really couldn’t buy more and even if I could, the color may not be the same. The 14 balls were 686 yards, too much for a scarf and not enough for a shawl, at least the size shawl I like – at least 20” wide (24” on the loom) and around 90” long (a warp about 3.5 yards long).

Assuming I would keep the beat at 12 ppi, as in the previous shawl, how much fabric would my Angora make? 

Here is my thinking; 1” of fabric would need 24” times 12 ppi which is 288” or 8 yards; 686 is enough to make ~86”, which would be less than 80” after shrinkage, way shorter than 90” ...Uhmmmmmm…

Meanwhile I was thinking about the warp. At first I thought of using a colorful warp as I did in the previous shawl, just not the same yarn, but nothing I tried seemed to work well; the Angora had too much pink for most yarns I had. Finally I thought of trying black and that was the answer. I had a large cone of Jaggerspun Zephyr, 50% wool, 50% silk. I don’t weave much with wool because of our warm climate in Mississippi, but owning a warm shawl for some cold (relatively) nights going to a concert or a play would be nice.

My thinking is usually circular; so while I was pondering whether I had enough weft and what I should use for warp, I was also thinking of what pattern I should use. I wanted something I had never used before. This was going to be woven on my 4 shaft loom, so Davison is my go-to source. I found the long rib weave, as she calls it. Here is the drawdown:

The floats could be a bit long, so I would set the Zephyr at 24 epi; I had plenty of warp yarn for 24” wide on the loom and 3.5 yards long. The weft however….

How about some Zephyr stripes? But how much?

To weave 94”, I would need 8” (94” – 86”) worth of Zephyr stripes, or approximately 1” of zephyr for every 12” of fabric, or ¼” for every 3 inch of fabric. 

Confident that I wouldn’t run out of Angora, I warped the loom and, after starting, I thought I would make my life easier by weaving 9 repeats of the pattern with the Angora and 2 repeats with the Zephyr.

As I said, I am not used to weaving with wool, so my challenge turned out to be keeping the beat light and even. I tended to beat too hard, even with the tension on the warp lose. I ended up making myself a 3” cardboard ruler with 12 epi lines so I could easily check the beat.

I am pleased with the shawl! It was finished in early August. It is 21” wide, the slightly wider width the result of the take-up and shrinkages less than planned (~6% rather than 10%); the 94” length was mostly from less take-up, about 3%, with slightly less shrinkage, ~ 5%; I do like long shawls, thus the extra length was a bonus. It’s still in the upper 80⁰s here, so it will be a bit before I can wear it, but here it is!
