Do you have a fabric shop near you? I have used several different methods but I suggest you try a few and see which one works the best.
1) a product called bubble jet 2000 in my opinion the best product on the market....however not the quickest or easiest.
2) Milliken Printed Treasures fabric sheets this is the easiest as the sheet are ready to go right into your printer. Everyone I know who has used them has been happy.
You don't have to have anything to special to do this. You will need some way of getting the pictures to your computer and some program that will allow you to edit or crop your photos to a pleasing design. Then any inkjet printer should allow you to print. Printing on the fabric isn't any different the printing on paper.
The next thing would be to determine how many photos you have to put in the quilt and the maximum size of your pictures. Once you know that I can help you design the size of your blocks and how many you would need.
