I love the pattern but had some trouble actually figuring out what colors to purchase for the 13 fabric version. I went to MSQC and browsed all of the Kona cotton colors and tried to figure which colors would work. I ordered all 13 colors + white. The hardest were the in-between colors. I think of this as the most challenging part and I am excited to receive my fabric and begin the quilt- crib size to hang. The colors are beautiful!
