Wow thank you SO much!
Mishti, I looked through my supplies, and I already have that little metal ruler you're talking about. I never knew what it was really for. I'm going to try that, combined with Patchwork's suggestion of using a tool to hold it down, and see what happens.
If i still need the smaller iron, I noticed that Joann's has a sale on them this week, so maybe I'll check it out.
I appreciate your suggestions! Thank you thank you!
