when we moved into our new house i started a new job- on the night shift- needing to sleep during the day- and summer time to boot---
i made curtains for our bedroom---that work as well as any black out's
they are simple large block pieced- dark blues-
then i added warm & natural batting and denim for backing (found on sale for $4 a yard-60"wide- at fabric.com)
i think i have about $20 into them and they are great---people come by-notice them and are always wanting to know where i got them :)
