I drew an Arkansas Razorback and enlarged it to do an embroidered whole-cloth quilt as a wedding gift several years ago. I took my drawing and had it enlarged at Staples -- no problem. Of course, the prime difference here is that it was a drawing that I drew (and it took me months to get it right since I was working full-time). I had a request from a member here a few years later and I took the drawing back to Staples and got another copy made to send to her. I've also taken surveys (certified copies) to the blueprint shop to have copies made -- no problem.
