If it is not out of your way, you need to stand up to this lady. Take your quilt with you when you go to talk to her. Tell her firmly but nicely that you had paid the agreed price and that she did not have the right to demand more money from you. Tell her you need the $50. back, and that she needs to finish the quilt or refund the rest of your money. Tell her that the two of you had a verbal contract. If you don't confront her, she'll do it again. Perhaps you're not the first one she's done it to. She can quilt an oversize quilt on her frame. It takes a little more effort and you do have to turn the quilt a lot, but it can be successfully done. You select the top edge and one of the corners and follow that corner down it's side. On the opposite side you let the quilt top
drop off the inside edge, and you clamp throught the double layer of the quilt sandwich. You continue to quilt like this until upu get to the bottom. You unpin the top and bottom and slide the quilt over to where the remaing top corner is in the quilting area along with the top edge. You repin, allow the excess quilt on the other side to drop off. You can clamp through a double layer of quilt sandwich, and start quilting where you left off and continue down the length and side of the quilt till you get to the bottom. :?:
