The top pic. is my original - gouache - using it well diluted with a sponge on a stick (!) and then underneath pics. are a couple that have been Photoshopped.
This is a small collograph using scrunched-up tissue and small bits of card, glued on to card, then painted and printed on to the paper. It's a really simple way to make a print, and you can manage to get a few prints out of it, even if you dont PVA it first. (Still need to do a bit more work on it though).
