The big challenge was using hot water to melt the wax without damaging the rayon fibers! I ran it through a gentle cycle in the washing machine with two rinses, but when I pulled it out, there was still a lot of wax adhering to the fabric, and I had gobs of wax in the bottom of the washer! I tried hand rinsing with hot water in a bucket, and it removed some of the wax, but I ended up running it through another full wash with hot water... then the wax was finally gone. Here's the finished piece:
Although the fuchsia dye faded, the other colors remained strong and clear! I'm very pleased with my first experiment with wax on rayon... hope it's only the first of many!
