I am making a Red Diamond quilt in November. It takes 1/3 yd of 21 different fabrics, usually flowers. I am using Batik's and traveling to Oregon, buying my fabrics along the way. So far I'm very pleased and only have 4 to go.
It's good to have a stash with different colors, but I like to buy background materials and keep on hand and batting when it's on sale. All this takes up space, so shop accordingly.
