Well, it was actually play with paint, but surface design sounds fancier. One of my goals for 2017 was to build on fabric I had printed with thickened dyes at a workshop last fall. For no reason I can explain, the dyes faded a lot on some of my fabric when I washed it, especially ones made with a soy wax resist.
A recent paint play date gave me a chance to improve them. Participants brought a wild assortment of objects to print with. Some were ad hoc such as springs, cat toys, chop sticks, bubble wrap, and rubber door stoppers; while others were purpose made, such as stencils and fancy foam brushes. I availed myself of many of these tools, plus empty toilet paper tubes, truly the Swiss army knife of printing.
