I keep a pile of freezer paper foundations near my sewing machine: when I feel like just "doing s-g" I can whip up a few PP log cabins or string blocks. I fold the paper, not stitch through it so the foundations can be used many times. I've made 3 quilts like this and soon have enough blocks for another without really noticing it!
