I agree with $12.00. Remember they take time to sew. I Made some quilted tote bags years ago for a co-worker. I charged her for the fabric. I later found out she was selling them, not gifting them. lesson learned for me! Isn't it terrible to have to be so cynical about everything these days. Now I charge for my time and if it is to much for someone, they don't have to buy.
If they were a lawyer or beautician they would not work for free.
