Those are way too pretty for pot holders! Maybe make one more, add sashing & have a small wall hanging, or make one more, set them on point & have a small runner?
I agree -- too pretty for pot holders. Sash and border for a wall hanging. You could put a pocket at the bottom and make a place to put your Xmas cards.
If you look at the picture under my name, I used Deb Tucker's ruler to do that Lemoyne Star quilt. The ruler is great to work with! I love your holiday star!
