The side effect of collage at the end of my desk looks nice but gets in the way.
Making collage is very satisfying, it's very crafty and structural and makes a good deviation from drawing for me. I must use very light paper, I can't stand there being a bump in the papers when they're pasted down and the heavier the paper, the more chance there is of this happening.
A can of spray glue sells for the price of a slab of beer and if the nozzle clogs, you must find a new nozzle or throw the can away. They don't sell individual nozzles. This is why the Russians took a gluestick into space.
