I have made tons of charm quilts - I love them. Charm packs usually come with 40 pieces. You can make a nice size lap quilt out of 1 pack or use 2 to get a bigger quilt. You can use 2 packs to make a stacked coin quilt. If you would like to see photos of some of the quilts I have made with charm packs I have them on my blog. Another good site to look at is ModaBakeShop.com.
