One of my customers (son worked for catering service) gave me a BIG bag of table cloths and napkins that match. Some round some rectangle all different sizes. Some of my family took a few but I have a bunch left. They are different colors and probably pollyester. I want to do something with them ,but don't know what ???

Do any of them fit any of your tables?

If you have an embroidery machine, it would be a great medium to embroidery with different themes, etc.

If you don't have an embroidery machine, you could applique on them with different themes.

Then you have a bunch of nice tablecloths for yourself or as gifts.... :D

placemats, table runner, dresser scarves. I wouldn't use poly for a quilt but you can make quilty things.

I'd cut them into fairly large squares, maybe 10-12 inches, and make quilts for times when you don't want to use your special creations. Maybe even use a whole tablecloth for the back. I had a picnic quilt made from the legs of DH's old work pants (polyester) that got a lot of use until it disappeared. Or you could donate the finished quilts. Bet there are lots of people who would appreciate them.

Any little boys around? I've taken sheets and drawn/painted roads and such on them for hot wheels cars. You could do that with a table cloth.

I bought a square table cloth to make a blouse out of.never did!! there was a pattern. i don' t think i ever got it.
make them into picnic table cloths and larger ones to sit on the ground.
