I have made & sold way over 30 microwave bowls & have an order for 6 more. I sell them for $8.00 each. I taught my DD #3 how to make them & she is selling them like hotcakes now too. She sells hers for $10.00 each with no problems. Can't understand them not selling at a craft sale unless your price was to high. The price you ask for them may depend on the area one lives in. I make mine with a 12 1/2 inch sq. Most everyone else uses a 10 1/2 in sq.
