Thank you for all the replies and tips! And sorry if I keep using wrong terminology, as I am still fairly new to quilting. :)
I did look at the snowball quilts, and the ones I saw all had round snowballs, is that right? The photos I have would lose a lot of their charm if I had to cut the corners, which I am a bit worried about, but I may try cutting some pattern pieces on paper.
I also looked at the Disappearing 9 Patch and am quite taken with it, so will try to hunt down a pattern and see.
I really hope don't mess this one up... :?
