I love both layer cakes and jelly rolls when I want to make a quilt in a hurry. My favorite pattern for layer cakes is Jenny Doan's "Alternating Squares". Her "Jelly Cakes" which uses both is another favorite. I enjoyed the 2012 Jelly Roll Quilt Along. There are so many fun quilts that can be quickly made with percuts! I have lots of charm packs; but haven't gotten around to using any of them.
