Dan,
This is a great idea for her. You know we want to see the finished product.
Also the Bob Marley quilt I did was done with the pre-done fabrics you can buy at any fabric store. Just be sure you let the inks dry before working with them.
This is how I did mine.
Crop the prints like you want them. If the pictures are sort of small and you think you will need some added color around the edges instead of white, put it in there before printing your pictures. I use a program called Print Master to do mine because I'm able to add background colors to the page before adding the pictures on top.
Then I print the pictures, most of the time I have several on a page but be sure you leave enough room between the pictures for seam allowances. I spaced mine 1" apart or more.
Once the pictures are printed, let them sit to dry real good. Usually within an hour at most.
Remove the backing off the fabric. Heat set the pictures onto the fabric.
I then use a mild solution of washing detergent in the sink and gently hand wash each printed page. This removes the extra inks. I some times wash them 2 times if I notice a lot of ink coming out.
Then I lay them flat on a towel and roll them up to squeeze the water out of them. You do not want to ring them out as this distorts the fabric and is hard to get them straight. Ask me how I know! lol
Once this is done I unroll them and stretch them into shape and let them air dry over night and then iron them before using in the quilts.
Here is a link to my Bob Marley quilt if you want to see how mine came out.

Good luck!
