Andrea - Not sure if that was a real question about how you do them? But as I hear fortune favours the brave, ill carry on. Basically the original polaroid 669 film etc is very easy, drop the print in boiling water for about 4 minutes and you see the emulsion starts to seperate from the print and after a bit of messing about it its easily worked off the backing. You need to be quite gentle with it as its fragile - then you need to wash off the nasty jelly chemical stuff that is underneath the top layer. Then you can slip paper/card underneath it and work it into position. leave it to dry then flatten it with a book overnight.
Newer films like 125i - it can be done, but a lot more hit and miss and not as easy, a lot of experimentation around times is needed and i havent nailed it consistently as yet. If anyone has....now would be the time to share!!!!
