The sheets pilled badly after only a few washings. I had ordered 2 other sets several years ago. Am still using one set, the other set finally fell apart from use. Neither one of them pilled like the newer set. They feel like sand paper. I am returning them and reordering another set.
I think you flannel sheets are good quality. They are soft and wash well. You have accomodated the thicker mattresses with your fitted sheets. What about the top sheet??? It needs to be bigger so that it can be tucked it.
I would recommend this product. I have a few sets of these sheets. However, they do fade and shrink. They may not shrink in the washing machine, but they do in the dryer. At minus 14 degrees outside I'm not about to hang dry them. ;-) But I love the colors and will deal with the shrinking and fading till they hopefully improve that. Very soft and cozy. Nothing like slipping into the thick flannel when it's so darned cold out.
