We've had this king size flat sheet for years. It came from a fabulous sale at Yonkers. The kind of sale where they mark things with dots, if I remember correctly, and this was on a black dot sale.
I found it in the linen closet when I was looking for something else and thought it just may make a nice curtain around my work bench.
Hmm. I like it here. It isn't very practical for messy projects, but it could easily be removed for that.
So, for now it's staying as a tablecloth.
