I bought a bag of 3 inch blocks for $3.50 in 8 different yellow fabrics, 185 total fabrics.. Also purple and beige bags too. So while I am piecing, I use these blocks as leaders and enders. Tonight I took two that were sewed together and matched them with two different prints so I can sew them together tomorrow into 4 patch blocks. I was able to do this while watching NCIS and now I have threads all over my sweater.
