I haven't done much starching. I just decide that I am making wonky things if they go that way. hehe
At a free motion quilt workshop, the treacher said she starches before she cuts, starches when pressing any seams, starches when pressing the blocks, starches when she presses rows, and starches when she presses the top. She also starches the backing fabric. Said it cut down on the movement for FMQ. I can see why, she's quilting a board! But that might even help me not have wrinkles.
