I love them, I am addicted to them. You can do so much.
Look at the book Jelly Roll, and you can see so many
quick and easy quilts that look like a million when your done.
The Charm packs are great too - I have used them for the
disappearing nine patch, and coasters, and totes, table runners,
and placemats, its so great because it all coordinates,
Buy lots, and have fun.
