I was thinking of replacing the covering on my design wall. I'm using a nice thrift store beige flannel sheet and it has served me well, but I really wanted something with a grid to help align patches & blocks. They do sell gridded flannel for this purpose, but it's pricey. I went to the thrift store today and they had an 8 yard bolt of flannel printed with a grid for $5. Could not resist. I just washed it with double fabric softener and it came out very soft with a nice nap. I measured it in several places and even though the lines are printed not woven, they are very consistent. I'm pretty excited. I hope to have some time this weekend to seam it up & replace the current covering.
