There is still time to register for upcoming workshops and seminars at Convergence 2016 in Milwaukee. Weavers come from all over the world to meet and study at this bi-annual conference sponsored by the Handweavers' Guild of America.

Yes, I will be there! I'm teaching a 3-day workshop, "One Warp, Three Fabrics: Weaving with 60/2 Silk," that focuses on how to weave with fine threads to achieve three very distinct samples. The first is a structure of twill blocks, using a 60/2 silk weft -- suitable for light garments and scarves with wonderful drape. Here's a student sample from the workshop I taught at MAFA in 2013.

Beautiful, I agree! The second sample we will weave uses a plain-weave structure and a silk-ribbon weft to achieve a fabric similar to that of rag rugs -- but in this case, far more elegant. I recommend people use this kind of fabric for jackets and vests.

The hand is lofty, almost spongy, which is part of its appeal. The last fabric is great fun: a collapse weave using an overtwist weft woven in twill blocks. The fabric looks like gauze on the loom but shrinks and collapses after washing. This type of weaving works for garments and scarves and can add immensely to the texture of any piece when combined with a 60/2 silk weft woven in plain weave, as shown in the photo below.

Here's a closer look at another fabric, woven with a similar weft.

There are 18 students signed up for the workshop to date, so I have been VERY busy winding warps. I will hand-paint them -- color just adds to the fun, even though this workshop focuses on texture and structure.

The second course I'm teaching is completely different from the first: It's a one-day studio class focusing on shibori techniques with natural dyes, appropriately named "Sawdust, Leaves, and Bugs." We will use some basic shibori-resist techniques as we work with osage orange (sawdust), indigo (leaves), and bugs (cochineal). The silk wrap below was dyed using these dyes and techniques, in a 6-step process. I began by immersing the silk in a vat of osage orange, then I clamped it and immersed in in a vat of cochineal (creating an orange color), then I folded it and immersed it in indigo (which produced green when added to the yellow and orange). Next -- and I believe that I did this twice, once on each end of the fabric -- I rolled the piece on a thick rope, scrunched it up, and immersed it in indigo. Finally, I dipped one end of the fabric in indigo. 

I find that the best results come with multiple clamping, folding, dipping, winding, etc. The takeaway from all of this is that more work produces better results!

And then, on Friday, I will be teaching a 3-hour "Super Seminar" on "How to Make Dorset Buttons." The technique, which was developed in Dorset, England, in the 17th century, is still useful for fiber artists today, as we can make custom buttons to match our creations or custom pieces to wear as brooches or clasps. While there are many modifications in making these buttons, I will be teaching a basic technique known as the Wagon Wheel.

Above, embellishment with beads adds to the whimsy of the piece.

So far, I have my class list for the 3-day workshop -- and I'm delighted to see that it includes folks from 10 states and Canada. So excited to meet everyone and watch the creativity unfold!

Scenes from a Class on Shibori with Natural Dyes

Two samples of arashi shibori on cotton by Joan Rusitzky, 

using osage orange (gold color) and indigo.

"Sawdust, Leaves, and Bugs: Shibori with Natural Dyes" is the full name of the class, a workshop I taught over the weekend at the Weaving and Fiber Arts Center. Students brought in cellulose fabric (cotton, linen, rayon, and silk) for dyeing in three different vats: osage orange (for golden yellow), cochineal (for magenta) and indigo. We also did some discharging of dyes, using RIT Color Remover.

The results were wonderful. Students went from vat to vat, clamping, tying, stitching, folding, and otherwise creating shibori resists that allowed colors to blend or contrast in a number of patterns.

Above: Barbara Mauger dyed a silk scarf, beginning with a base of osage orange 

(made lemon yellow because it was simmering in a copper pot), 

then clamping with spiral forms and finally dipping in an indigo vat. 

The red color on the lowest spiral comes 

from a bit of old dye that was still on the spiral resist.

We learned that natural dyes could successfully be discharged using RIT Color Remover. I had used this often on man-made dyes but had no practice on natural dyes. Nor could I find anything online to document that it would work. So we found out for ourselves that it was effective, with the vat being hot enough (about 160 degrees Fahrenheit) and enough time elapsing (at least 15 minutes) for the fabric to sit in the vat. Another insight: Michel Garcia recommends that cotton fibers will work better in natural dyes if they are pre-mordanted in aluminum acetate rather than the traditional aluminum sulfate mordant. I looked this up online and found that an over-the-counter pharmaceutical product, commercially named Domeboro, is made of aluminum acetate. That's what we used, at approximately one package of Domeboro per one ounce of fabric. It worked great!

Typically, it's hard to get saturated colors on cotton fabric using natural dyes. I believe (and this is not based on research but rather on my own assessment) that it does help intensify the colors.

Eleanor Hartquist used long cords to scrunch up her fabric, 

which we think was either cotton or linen. Not sure. 

The brown color you see here was a base color, 

achieved by dipping first in osage orange and next in cochineal.

 then again folding and clamping it and immersing it in indigo.

On the final day of class, just for fun, I made a vat of onion-skin dye, which produces a lovely golden/rust color. Below is a photo of some silk yarn that Eleanor decided to wrap (an Ikat technique) and immerse in the onion skin dye.

may be skewing a bit toward the red end of the spectrum, but you get the idea! 

Lots of fun and color for a December weekend. I'm thinking of presenting anther workshop along these lines in the future, perhaps using madder, onion skins, and woad. Let's see, that would have to be named "Roots, Peels, and Leaves...." 

Shibori with Osage Orange, Indigo, and a Bit of Cochineal

The fabric is a cotton/linen jersey I bought from Mood (the official fabric store for Project Runway) in New York City. Above, a detail that shows a color I take great pride in: turquoise! It doesn't appear throughout, of course, but if you look at the shading on the perimeter of the golden rectangles, there it is. Turquoise is hard to achieve with natural dyes, at least for me, and yet it's one of my favorite colors.

"Sawdust, Leaves and Bugs" is what I like to call the combination, and it's the title of a course I hope to teach soon at the Weaving and Fiber Arts Center. First, I immersed the entire fabric in a vat of osage orange dye, purchased from a friend, David Barnet, who is a master woodworker with the Rochester Folk Art Guild. (For more on this talented group of people, click here.) Second, I did some tying and clamping -- using techniques that are jokingly called "dirty shibori" -- before immersing it in a vat of cochineal. In this case, the cochineal wasn't as bright, perhaps because I used the vat once before: It doesn't really show up on this fabric, other than lending a red-gold hue in the center of the rectangles above.

The last and best part, of course, was to dip the fabric five times in an indigo vat. Before dipping, I used a number of shibori-resist techniques: arashi, where I wrapped and tied it around a piece of PVC pipe; knotting, in which I simply tied four overhand knots in a length of fabric; folding and clamping with rectangular blocks of wood; and folding and securing with closepins.

My favorite results are on the back (pause for snarky comment: of course), where I used the arashi-shibori technique of wrapping the fabric around a PVC pipe and then tying with cord.

I made another top, using similar techniques, and the results were completely different. My thinking is that the amount of fabric exposed to the dyes was very different in the two garments, which meant that the color blending was entirely different as well.

Sawdust, leaves, and bugs yield wonderful results! Thanks for reading!
