Wow. Tish...that jacket is beautiful.
So, from what I'm understanding, regular machine embroidery thread is fine for threadpainting, Trilobal is better and some people (Joyce Hughes who I will be taking a class from in November) use cotton.
Also, Feline Fanatic..did you see that your manufacturer for thread seems to be not going to carry that thread anymore? It's all on sale and they aren't getting more. Might be a good time to stock up!
