Monofilament thread
I am working on an applique project & I noticed one of the swaps on line specified not to use monofilament thread. My mailbox was full & I never got her response. I ironed the thread with a very hot iron, it is 100% polyester thread, which I was going to use from my embroidery threads anyway. So my question is why not use monofilament thread? any help will be appreciated
