I'm Twisting again!!!
I bought the Itty Bitty Primitive Pinwheels pattern with a template last summer. I finally took time to make it. It finished at 10 inches with each block 1 inch. I don't think I will be making it again in the near future. If I ever do, I will press the seam open. It is very thick with all the seams pressed to the side. I did press them open after joining the blocks but didn't when I made the blocks or joining the rows.
I also bought two charm packs to make a heart twister with the Lil' Twister template. It was so easy after working on the "Itty Bitty"!
