I don't know how many of you might be interested in this but it started my wheels turning when I found it:

Custom Fabric Printers:

You can get any design you want (designs that you email them) on 60# Broadcloth fabric, one large image or many small images (tiled), however you set up your piece in Photoshop is how they'll print it. $18/yd (42 x 36). This is cheaper than a print on paper of the same size!
