welcome from Oklahoma.
Keep plugging away, you just have to remember that there are over a zillion quilter's in the world and they are all trying to SELL something these days! Quilts are no longer considered RARE, as they are found everywhere now, so that alone makes them, hard to sell. Quilts being mass produced in 3rd world countries for pennies are hard competition to beat as well!
But if your workmanship is good, your designs original, and your prices fair market value, and you keep plugging away, you will get lucky sooner or later!
