He does not have a name, but he is very handy.
If you have a plain, store-bought pincushion that rolls around all over the place, I highly suggest that you do this to hold your pins where you want them.

I’ve got an old ceramic frog, one of those old-timey sink sponge holders. I’ve simply stuck a store-bought pincushion in his mouth–voila!

Because he’s nice and heavy, I can set him beside my sewing machine and blindly stab the pins toward the cushion while I’m stitching away. He doesn’t move or flinch, and doesn’t roll off my desk. The neglected frog becomes helpful once again (and mighty adorable, I might add).
