Patrice -- that is sew cute as well as practical!! However, I have no clue as to what you should charge. However, it would make a great "class" and you could probably charge $35 per person and then give them a copy of your pattern. Or sell the pattern for $8(?) But you know how conservative (spell that "cheap") most of us quilters/sewers are, I don't know what you should charge for the finished product.
