I need to chime in here also ... I too had an error in cutting some fabric. I ordered a 2 yard cut, and was shorted 1/2 yard. I emailed and let them know. I got an immediate response email and within TWO days time, I had a whole 2 yard piece in my mailbox, and was also told to keep the error.
Love that place! Quality of fabric, customer service, the whole thing!
