I've been looking at the Rust-Tex website since enjoying their display at Festival of Quilts and found this lovely piece of work, Koi. Here's the detail of one fish:
During the winter months I am driven from my outdoor dye studio by snow and low temperatures. I spend winter using the fabric I rust dyed in the summer. These koi were stenciled onto a fat eighth of Rust-Tex using a commercially produced stencil. I used the colors Bronze and Pewter from the Lumiere line of Jacquard brand fabric paints. 11"x18"
I found this so inspiring I thought you would enjoy it too!
