As I was lamenting how narrow and expensive flannel is from the fabric store, it occurred to me that you could use flannel sheets for the backing instead.
Beth just made a T-shirt quilt (using all of her favorite t-shirts that she doesn’t really wear but didn’t want to get rid of) since she wanted it to be a light summer quilt she is backing it with a jersey knit sheet. The kids don’t use top sheets on their beds so the top sheets always end up in our fabric bin and we just happened to have a big gray one that she could use. These sheets are inexpensive at Target but they would be even cheaper and better for the earth if you were to buy them at the thrift store. I know it’s a little creepy buying sheets at the thrift store but if you just dump them in the wash right when you get home maybe it won’t seem so bad.
The measurements for top sheets (with the hems opened) are approximately:
Twin: 66 x 96 which equals 1.8 yds x 2.6 yds
Full: 81 x 96 which equals 2.25 yds x 2.6 yds
Queen: 90 x 102 which equals 2.5 yds x 2.8 yds
King: 108 x 102 which equals 3 yds x 2.8 yds
Which would make for much less expensive backing than buying new material. Also you can always use RIT dye to change the color of a sheet if it looks to drab, which I plan on doing with a sheet that I just picked up at the thrift store for $.50.
