I love 5" charms because there are so many things you can do with them.
You can make a 10-Minute block quilt with them, or simply put them into rows in a happy arrangement and sash them, with cornerstones made of 2.5" squares, or pair each one with a solid (like Snow again) and make any number of HST designs.
I'm in the middle of a snowball quilt, in blues, with Moda Snow for the corners.
Have fun!
