I have used Printed Treasures fabric with good luck in the past. Recently I wanted something printed larger than the 8X11. I was doing a police themed quilt and wanted the patch I was given as a medallion around 10-12 inches in diameter. I found a site online that will print out to VERY large sizes! (depending on resolution of the picture...) I sent her my picture file and in a week or so, she mailed it to me. It was VERY reasonable...I think I paid $10 plus very minimal postage. I am not affliated with this company..just VERY happy! (the recipient of the quilt LOVED It) I will be using her for printing on fabric again! Here is a picture of the medallion quilted.

note: I forgot to mention that the fabric has a wonderful hand! I could not feel any stiffness from the inks.
