A sale is a good idea. I wouldn't cut anything--it is more work for you. $1.00 or $0.75 each for fat quarters sounds reasonable. Bundling them would be more efficient rather than selling them one at a time. $1.00 to $2.00 a yard is a good price for fabric, but I wouldn't cut anything. Selling on here is a good idea, but probably more work since you would have to mail everything. Good luck with your "sale".
