In my area, you wouldn't be able to sell them for $20.00`!!! I really depends on the location AND the workmanship.

There is a member that regularly makes them and you can even pick out your fabric from a few choice options.

I have made a few and my price is $65.00 if I get the fabric, plus the fuseable interfacing plus my time. It takes me around 8 hours to make one. I have sold a few of them. I told some one if they purchased the fabric, I would supply the interfacing and make it for $45.00, that didn't seem to be a problem at all.

I made one in my quilting class and it was sold before I could get the buttons on it. My sister has purchase 3 of them from me., plus they also make nice gifts.
