Quilt Sampler from Charm Packs (VIDEO)
This is a great way to flex your creative muscles and practice piecing on the fly.
These half square triangles are SO easy. Get a charm pack, cut some of the squares down into half triangles, or cut the 5 inch squares in half both ways to make a 4 patch, mix in some squares and play. Seriously, just play.
Then when you see a pattern you like, cut everything down to 4.5 inches, sew together, add sashing and make something that is completely and totally created by you!
