How to keep your work fresh: take time to play (with no ulterior motive).
Move things around, turn them upside down, pull out your crayons and be mindless with them, cut and tear things up, open a book you like and see what jumps out at you (like this one, by Katherine Dunne). In other words, just mess around. That's what I do when I don't feel like working, but I want to do something, or when I feel a little jaded and need to shake myself up.
I think that's what people do with their art journals, but that's not what I'm talking about. (I don't have the temperament for a journal -- I've tried and it just doesn't work for me).
I want to be able to grab a piece of paper of any size or staple a bunch of telephone book pages together to make a background, bring out my crayons (I have a mixture of Sennelier and Sakura that I've had for at least 10 years, and they are still going strong) and make something silly.
Where did the word mustard come from? What does it have to do with
anything? The yellow crayon made me think of mustard, so I wrote it
down. Later on I added "cut the", to finish off the expression. I did
say I was making something silly!
