Here's a video outlining the project I did for iHanna's 2010 postcard swap.
I started with 16 rectangles, 6"x4" from cast-off cardboard (cereal boxes, a calendar). Each piece was gessoed, then it was all put back together. The design was drawn with a piece of charcoal into wet gesso. When it was dry, I put a wash of blue over it and let it dry again. Next up, the shapes and lines were painted in and after that was dry, all of the pieces were cut apart again.
My idea was to create a whole painting from pieces. I wrote "connected" on the front of each card and then on the back it says "You are one piece of a whole." Each card is numbered: #1 of 16 and etc. It was a good way to push myself to work larger and I liked the idea of being a piece of a whole.
I am currently lying on the sofa with ice on my back. Too much snow around here; we've had 30" of the white stuff in under a week. Good weekend, all. Hopefully I'll be all repaired by tomorrow.
