I have to admit, right now all my sheets are in a wad on one corner of the bed. I went through a depression episode earlier this week and, while I managed to summon up the energy to force myself to strip the sheets and get them washed, I still haven't put them back on yet....

I only have that problem on corner number four. Folding is never a problem because I take it off the bed,wash it, dry it and put it back on. I do have spare sets and can actually fold if it is required but I avoid it whenever possible.
When the video link finally showed up I was glad that the cat knew how to help.

@Lorajay I can never remember which corner of the sheet goes where in order to make the sides match up. I always manage to get the short side hooked on the long way & vice versa on my first try.

@Paul4747 How can you remember? It's not like they're marked. I guess wrong EVERY time

@TheoryNumber3 I use a Magic Marker to put an approx. 2" star on the same corner of each...lasts forever, and sooo much more fun than guessing!
(I tried a smaller mark but it was annoying to find)

@AnneWimsey That's a GREAT idea, Ann. I'm going to do that.

@TheoryNumber3 There's a tag on one corner, stitched inside.

@Paul4747 Yes, and it's always the last corner you look at

That's the one!! I had so much trouble finding a version that would post here
