I'm attempting Mickey tie dye shirts for our upcoming trip again. I had really good results with the shapes on the previous two times I've done these. The first time the dyes were much more vibrant than the last time. The last time the dyes seemed to separate, instead of getting lime green, I ended up with yellow surrounding blue. Then with purple, I got light pink surrounding light blue. What dyes have you had success with? I'm looking for bright colors that won't separate. I was thinking that technique-wise, I could soak the shirts as directed and then let them dry out more, rather than following the dye directions and just squeezing them out and then dying. I have used 100% cotton tees, and also some 95% cotton 5% spandex. I also had trouble sewing the thread to make the Mickey shape. I think the first time I used very fine dental floss. I also tried a filament thread but that kept breaking when I'd try to pull it tightly. I have not been able to find basic "waxed thread". My sources for supplies are Michaels, Ben Franklin Crafts, and JoAnn's. TIA!
