The JD quilt is great, and starting with a theme seems a good idea, instead of looking at the stash and trying to make decisions.
I don't do theme's but I was pleased to see a new range of fabric (well new here in Aust.) with International Harvester tractors. My family had an engineering business and for many years held the International Truck and Tractor dealership, would be fun to do quilts for my grandson whose dad worked in the business, xxjen
