I use sheets all the time, both cotton and flannel. You do have to watch the quality and check the thread count. Some of the sheets at Walmart lately have had a very course weave and a low thread count (180). They are the ones that I don't bring home. I always buy the biggest sheet that I can and use the left overs to make a matching pillowcase or two. I found Dan River queen size flat sheets, 250 thread count made in USA at Len's Mills in Guelph Ontario (fabric, clothes, cleaning products, sheets, towels etc.) for $8.49. They are much better than the sheets made in Pakistan which are not consistently good quality.
