If you're always having trouble holding onto the base of your model with one hand while you paint with the other... try this out.
Grab an old paint pot or similar sized object and set a blob of "ticky-tack" (the stuff you use to hold up posters) or something similar on top. Press your model down into carefully and you're all set. Now you can easily hold onto the object and not worry about messing up your model with messy fingerprints.
