There are lots of ways of using your own photos, whether they are old family portraits or modern snaps.
If you fancy making use of your old photos and transferring them to your cards or scrapbooks, try Barbara Grey's tip, get some nail varnish remover (from Sainsbury's - apparently that works where others may not), a make up sponge. Do a copy (black and white) using your inkjet printer / scanner (you may need to flip it horizontally to get the final image the correct way round), lay that image on your desired media face down, dampen with nail varnish remover on the make up sponge, rub over with the back of a spoon, carefully lift the paper to see if the image has taken. If not continue rubbing until it does, then remove the paper from the top and allow to dry. Again, I have not yet tried this, but it is next on my list, although I did something similar as a centrepiece for an anniversary cross stitch, but that was done using a special kit.
