Thanks to everyone for the positive feedback. Sometimes it's nice to know that someone else appreciates what you do.
Arrhythmia, the paint is just acrylic craft paint. I use Delta brand mostly. I've not noticed a big difference with textile paint and just started using the regular paint instead. Sometimes I'll use the textile medium that goes with it to soften the paint a bit if the fabric isn't so sturdy. But I've never found a way to keep it from stiffening up. Fortunately, it doesn't matter for this project.
As for setting the paint, I just let it dry and then pressed it between plain paper towels (to protect the iron and board) with a really hot iron. Actually, the acrylic paint seems pretty permanent after it dries no matter what you do. Notice how spills and blotches on clothes never come out?
Thanks again for kind words. Makes my day!
