I've ironed a tiny piece to let you see the pattern. To achieve this, I simply "poked" my finger up through a section of silk, "poked" the center inward, took and stitch to hold it in place using quilting thread and tightly wound the thread around this bubble. I made these bubbles as close together as I possibly could before overdying the original color which was a soft robin's egg blue, with golden brown -- a little heavier in some areas. When I get a chance to play again, I'll dye the base using a mix of colors and then overdye again using a mix to see what happens! Great fun and what a surprise when you remove the thread. One hint: use magnifying reading glasses to remove the thread to avoid holes in the fabric!
I'm fascinated with shibori - there are many different types and I'm enamored with pole wrapping. Lately, I've decided I want to expand my knowledge and although I already own one fabulous book by Karren Brito "Shibori - Creating Color and Texture on Silk", I've ordered another from Amazon by Yoshiko Wada since I want to delve more into stitching and overdying. Some time ago, I purchased a piece of shibori cotton that fascinated me with the color pattern so I decided to make an attempt on one the soft robin's egg blue silk pieces dyed last week and this is the yummy result of overdying it with a golden brown acid dye. I'm thrilled. This is a small piece and the color is variegated throughout - more brown in some areas than others as you see.
You must leave it to dry completely before removing the thread. When I pulled the puckers apart, there is a definite pattern and I ironed a small piece to let you see although I do love those puckers! You can iron the whole piece to use as a patterned piece for a quilt piece or other project; however to keep the puckers and use it that way, just iron some lightweight fusible web to the back - when I get the time to experiment more, I'll post the results.
It began with the silk piece below and you can see what it looks like after stitching and over-dyeing.
