I recently watched a demo by Jane Davies
on YouTube where she made "abstract postcards"
by collaging different papers, crayons, etc.
on a 8 1/2 x 11 sheet of media board.
Then she cuts them in fours to get a wonderful
mix of patterns and textures.
I ended up doing four of them in different colors
and had them framed together.
(Sorry for the glare.
I didn't photo them before having them framed!)
I loved them so much, I kept them
and hung them in our sitting room!
