Prior to first use I washed the sheets and pillow cases in warm water and machine dried them. Typical of flannel sheets, they left the usual amount of lint in the dryer filter. Before placing the fitted sheet on the bed for the first time, I noticed one of the vertical corner seams had a 3-inch tear.
Arrived packed, and I thought the weight wasn't going to be that heavy. But after washing the sheets they did fluff up and the weight turned out to be very good. The 24" deep pockets on the fitted sheet is what we needed for our mattress. They are a good quality sheets. Stitched used in the sewing was set at about 10 per inch (so a bit wide). I hope I won't have to re-stitch them anytime soon? I'd have preferred a tighter stitch, but that's me.
Sheets are very thick, but not well made. I washed them before using them and the stitching on the bottom sheet was unraveling. Also, not deep pockets as advertised. I won't return them only because they have been washed and it is too much of a bother to return at this time. Not pleased!
