The process actually started reviewing some of the quilting books I have in my library. Two of the books had the half square triangle with the other half as stripes, in different arrangements. I felt this pattern was straight-forward enough to make good progress on in a short amount of time, and finish before the deadline in mid-September. The whole thing took two weeks part time. Your first quilt (this wasn't my first) will take longer. Trust me.
I read the play and then went immediately to the fabric store. That way I remained inspired while I was selecting fabrics. Most of the fabrics were from that one trip, with one fabric from my collection. Notice the assortment of lights, mediums and darks.
