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.
Or you can temporarily tape bits to a carrier sheet, remove and fuse these to a work in progress.
Carrier sheets can be as simple as a sheet of paper, freezer paper or even a flexible cutting board.
Try different things to see what you and your printer like best.
I like the effect of combining the different fabric textures in a single work.
I used this technique on Coming Back, now at the PSAQA's ARTQUILTS Illuminations exhibit in Durham, NC. It can be found on my website in the Digital Fiber Art Gallery.
