I have been immersed in a five day class on how to use chemicals to create designs on textiles -- otherwise known as discharging -- taught by artist Bob Adams at my favorite store, The Quilters' Studio, in Newbury Park.
The idea is to create multiple layers of design, using thiox, monagum, formusol, bleach, and anti-chlor as agents to selectively remove color from fabric. In Bob's piece, pictured above, the grids, freeform lines, and white squares were created by separate processes.
I tried several different chemicals on one design (a seated female), testing to see how the black cotton discharged:
