Depending on where you're selling them, dishrags and coasters. Cheap and quick to make (not for me, because I'm still slow). Sell them both as sets and individually...and show them in their "natural habitat"...use them! I gave a dishrag to my massage therapist yesterday and she couldn't believe you could use it! If you show how good a crocheted coaster sucks up the water (with a glass of ice water sitting on it), they should go well.
God bless your family for being faithful and trusting that God won't hand you anything he isn't going to help you with. Hugs and prayers going your way.
