What a great idea. I made a memory quilt for my granddauguter for her high school graduation. I incorporated a picture from each year of her life. Some were candid snapshots and some were school pictures. I had no means of doing the copies so I brought it to a copy store (Sir Speedy) along with yardage of muslin. They made color copies of the photos and then copied them onto the muslin. The lady who did the copies was a "sew-er" so she knew to leave enough space between the photo copies so that I'd have plenty of seam allowances. Since you haven't made the copies onto the fabric yet, be sure that you have space between the pictures to have a seam allowance. One more suggestion. If you have too many photos for one pillow, consider making more than one pillow. OR, put some on each side of the pillow. Another thing I did with mine was: I added strips of brightly colored fabric (or something that blended well with the photo) to form a mat. Good luck with your great project.
