A made a painting handle that accepts most and champagne corks for painting pinned models.

I like to pin my miniatures and mount them on corks for painting, but the corks themselves are just too small to hold onto comfortably.

The large socket holds a champagne cork snugly, while the small one fits a standard sized wine cork. Most wine corks will stand proud of the base of the handle, and I've cut mine down so the handle can stand upright on its own. Trimmed down like this, a based miniature can still be affixed to this end with poster tack, and the champagne cork can be removed.
