Clean, organize and inventory the workbench. Get your ducks all lined up. It is a good time to sort the spares, restock supplies, and clean everything top to bottom. Put things back where they belong. Rearrange it all if it helps! I do that fairly often, trying to find just the perfect setup for me.
Go do some other things that need doing as well. Tackle some of the other dreaded chores like a pre-spring cleaning of the garage...I back park the vehicles outside, close the door, bundle up in warm enough clothes, crank the music and putter around cleaning and sorting. I usually end up with a couple of full trash cans and more space to use. Again a good time to take inventory to see what supplies you'll need come spring. It's a good time to inspect the lawn & garden tools, I sharpen the hoe, shears, lawn mower blades...I oil the wooden handles...make sure my pump sprayer was cleaned before it got put away for the season. Check to make sure my cordless tools are fully charged (the cold weather is hard on batteries and many forget to take them indoors...oops me too )
Getting away from the bench can help keep you invigorated about modeling when you can return to it. Plus, getting some of those little things done now while you can't paint means you'll have that time free later when you can.
