This quilt is a great quilt for beginners. In fact, if were teaching a beginner how to quilt, this is the one I would have them start on. The pattern takes one charm pack and one layer cake. I got mine from Green Fairy Quilts, a terrific online quilt shop that has lots of precuts, just like these, to choose from. I chose the Somerset Collection by Moda.
The pattern is a free pattern by Craftsy, called Large Granny Squares. I recommend you download the PDF and print it so you can have it next to you while you are sewing.
P.S. Green Fairy Quilts sent me the precuts so that I could use them and show you how wonderful they look in a quilt. They have tons of other fabric lines that are gorgeous! If you haven’t ordered from them before, you really should go take a look.
