I have watched the Sue Daily video. She does do nice work. I'm not sure, but I would think that you would want to wash the project when finished to remove the glue. But then, I wash all my projects after they are finished. Especially hand worked things, just to remove body oils etc. Also, I tend to have the project go on for quite a long period of time, and I'm sure it's soiled. Even tho I try to "wash up" before working on it! I cut all my own papers so can't comment on the GO, but I would be sure the seam allowance is at least 1/4 inch. The glue pen looked very handy, but guess I'll just stick to thread basting.
I can't believe you machine basted your hexies in the first quilt. That must have taken a fair amount of time to remove the basting stitches! I don't remove the basting!
