I use a lot of ink jet prepared fabrics for my work. I purchase this in large rolls from inkjet fabrics.com (here). This way, I can cut the yardage to the desired size to print. This works out very economically and is less expensive than buying sheets. I do end up with a variety of different size scraps though. I have figured out a couple ways of using these bits.
You can fuse them to paper or cloth and print this as a collage that is ready to work on.
