We use a variety of surfaces for paint and collage, but primarily we use some kind of paper. As paint or glue is applied to paper, it pulls and shrinks it. On some collage projects, like the Kuitca-inspired paintings the children worked on last year, paper must be glued onto the back to balance and pull them back onto a mountable surface.
On easel paintings or on simple painted paper, I use an iron. If I have time, or rather if I don't have time to sit and iron, I use hollow blocks to flatten works. Some items take A LOT of weight AND time. We have a collection of large boards in the basement that we use to flatten works like the glue-washed easel paintings and the latest BIG paintings. After a few days these works, which before flattening would have resisted all methods of adhering to our walls for display, are ready to emerge like butterflies.

|I had to use several sheets of 4'x8' plywood because the BIG painting are so BIG! They have to be flattened because the paper's weight will pull it down unless the tape is able to attach itself evenly.|
