setting seams with iron first
I'm curious about first setting seams then pressing the seam to the one side. I understand pressing the seam to one side and nesting seams. But what about setting seams. Do you or don't you? And why? I've seen instruction videos where the seams are not set, they are finger pressed to the correct side and then ironed. The seams are not set. The instructor's blocks appear to come out perfect! Opinions please, and thank you in advance!
