Beth - I HATE folding fitted sheets. There are sites on the web that have articles as well as video's on how to do this.

I still struggle with it.
Now that they have put elastic around the whole border of the sheet, it makes it even more difficult to fold. Many times, I strip the beds, wash the sheets, and just put them back on the bed instead of having to fold.

Yeah, I shorty cut. LOL
I also "package" my sheets when I fold them. I put the fitted sheet and matching pillow cases in the last "fold" of my top sheet. Then everything is put together and we just pull out the "package" when changing our sheets.
