I'm working on making a bunch of 9 patches using strip piecing to sew 3 strips together before cutting and sewing into 9 patches.
I know that you aren't supposed to iron a block but to press it to not distort the block.
What about when you strip-piece though, do you iron the seams along the length of the strip or only press? I've been ironing along the length but wondered if maybe pressing would make more accurate blocks.
