Here is a collage of some of the tissue paper I have been painting. (I did this in Picasa, not in cutting and pasting real paper! Not yet, anyway.)
This is a photo of some corrogated card which I painted. It looks like a Picasa collage on its own!
And, a bit late, here is the best rusted piece from the baking tray which was up in the loft catching the drips. It is ironic, really, because it is a practice piece on which I was trying to transfer a picture printed on Lasertran (not very successfully).. but I think it looks like one of those old medieval maps. Pity I could never repeat it if I tried!
