I guess I'm not too fussy on bedsheets. Probably because when I grew up, these things weren't a priority for spending (e.g. not at all), so we had million year old threadbare cheap sheets. So I know no different. J was the same, so we combined our collection of million year old threadbare cheap sheets when we moved in together. Towels are the same. We've now got two really nice (probably what none you of like for sheets) duvets from Debenhams and they feel awesome. We also got a set of towels from M&S for a wedding gift and wow, they're comfy. That makes me think we should probably have a big ole clean out of the million year old sheets and towels.
Way back in time, 60+ years ago, some of my relatives worked for Cannon Mills in Kannapolis NC. We always got sheets & towels for Christmas & wedding presents, and our family was among the first in our little community to have patterned sheets. We also lived 30 minutes from Fieldcrest Mills (also in NC) and they had a fantastic outlet store. We always had nice sheets and towels, and that's something I truly appreciate.
I also need to have a towel clear-out. I bought some plain white towels at another factory in Roanoke Rapids NC back in the mid-1980s, and they are still usable. By contrast, some towels I bought here a few years back which looked/felt great went ragged very quickly.
I mourn the death of the textile industry in the US, but for whatever reason, it seems the imported stuff now sold there is far better/cheaper than I can get here.
