I have not been happy with pressing the blocks and maybe it is because I have been doing it wrong, or not remembering how I was taught.
I was using a thin dish towel, dampened and then laid on the appliqué block which was face up. I got all kinds of funny wrinkles, that I would then try to get out with the iron and I wasn’t very successful.
It came out beautifully! This was the August block, which really did have strange wrinkles in it, now all smooth and straight. So I pressed all the others, much happier now!
So let me know how you press blocks or if the face down method works for you.
