These curtains were an effort to block the summer sun from heating up my new south-facing attic sewing room. They were also an experiment in using the ruffle foot attachment on my old "vintage" Singer Model 15 sewing machine that was my mother's. It worked great, and I had fun. I used a blackout lining to hopefully help block the heat.
2 yards cotton fabric
2 yards blackout lining
3 yards cotton cut into six-inch wide strips for ruffles
Total: 7 yards from stash.
