I charge .065 per square inch. For example: A quilt measuring 65"x70" would cost $295. This size quilt would require 30-40 items of clothing.
I just require a $100 down payment to confirm your order: http://www.etsy.com/listing/89356672/down-payment-for-custom-orders
Pictures and/or names and birth dates can be added as well to these quilts for a n additional fee. Send me a convo and we can discuss what you envision your quilt to be and I will give you my address to send your clothing to!
