Several weeks I lead a workshop for the Tampa Bay Surface Design Guild on over-dyeing fabric. Students bought in fabrics they had previously dyed and learned how to over-dye them. We discussed color options and manipulations options. I had premixed all of the single color dyes for them to use. Here are a few pieces they created.
Bonnie Ward before
The last three pieces by Bonnie shows the original piece before over-dyeing (the small swatch) and an almost solid piece of the color and the larger over-dyed piece. In addition to over-dyeing several pieces, Bonnie took the time to dye samples of all the single color dyes. Now she has a great idea on how the colors interact with other colors and a great start on creating a dye notebook.
