I am a lover of precuts even though they are more expensive. Today, however, I cut my own layer cake. I am using a pattern that calls for a layer cake. It did not take long to cut the 10" squares and I had a good variety of fabric to use. That is usually not the case and I like the variety of fabrics in pre cut packages. I use jelly rolls, charm packs, and/or layer cakes when I want to make a quick quilt.
