Most throw-sized quilts on etsy go for a minimum of $200. If they're not willing to pay you for your time and talent, I wouldn't do it. If you just calculate the time you spend, at $150, you're only making about $10 an hour- seriously? Quilting is too labor-intensive, not to mention that you have to know what you're doing, to give away, u less its friends and family or charity, and you don't mind.
