We can use old sheets to make you exit pillows and curtains if they are still in good condition
I recently used sheets to make my patchwork curtains. You can pretty much use the fabric to make curtains, pillows, quilts, tablecloths, table runners, etc...
Funny you should ask as I am just now in the process of washing my curtains which are made of sheets. Just rehung these curtains, and am soaking the shade in the bathtub. Will do dining room curtains next. I would not use worn sheets for curtains though. I love Holly's idea of the patchwork.
