You could send them to spoonflower.com. They do custom printing.
You could also buy those fabric sheets (8 1/2 X 11) that they have at Jo Ann's (and other places). It works just like copy paper. You could copy the line drawings to a file and print them on your home printer. I would try this first on a small package before purchasing a large amount (it's fairly expensive). I made some quilt labels with it and it was difficult to get a needle through. I didn't wash it before putting it on the quilt, and that might solve the problem. It was doable, but I would not want to embroider it. (I just blind stitched it to the back of the quilt, but I had to use a thimble to get the needle though the fabric.)
