Do you have any hints on pressing strip sets? I'm working on six strips in a set and each strip is two and a half inches. I need to press the seams to the sides, and some need to be pressed one way and some the other so they will match when the sets are sewn into blocks. I would like to get a nice, crisp seam every time without pulling and tugging those seams when pressing. More often than not I get a tiny fold of fabric over the seam line. Any advice would be appreciated.
Also, I'm using a cordless iron on high. It doesn't seem to get as hot as a regular iron. Could that also be part of the problem?
