I have a dumb question, but wanted to check. When we send our fabric it is requested that we use fragrance free soap...I'm good with that, even rewashed the fabric I've pulled for the blocks. So the question is, what about using starch/or alternative? I've gotten in the habit of starching fabric for blocks because they cut and sew so much better. So is it okay? I use unscented Best Press...do you make your blocks with or without? Look forward to the responses.
