I am making a quilt now with precut layer cakes and found that they shrunk when washed and I had to really be careful when cutting the rectangle and squares I needed. But the advantage to the precuts is that I will make a second quilt from the same fabric but the placement of the patterns will be different. The quilts are for my 4 and 6 year old granddaughters who share a room. The pattern I am following is a 64 x 64 inch square, so I had to add other fabrics to make it a twin size.
