Things that make a sweet workspace:
1) Good Lighting: I think a funky industrial light would be a good choice.
2) Comfort: An old comfy couch is a must, for daydreaming up brilliant designs, or staring off into space, or maybe an inspirational nap. (I would love to try and take on this patchwork re upholstery project myself...fun!)
3) A functioning work bench: Here are some benches in other working artists studios for inspiration.
These next few weeks I will be busy putting something similar together for myself. I can't wait to post before and after photos of my work space, because that will mean that I can get to work!
