We also had a pair of leather crib booties that we aren't using anymore. I had gotten them to protect Addy's toes so she wouldn't accidentally chomp too hard on them during that disgusting developmental phase where babies start sucking on their toes. Nora kicks too much and won't leave anything on her feet, so she doesn't wear them either. I cut off most of the side and heel, and cut three holes along the outer edge of the sole (1 for her thumb, 1 for her pointer and middle fingers, and 1 for her ring and pinky fingers). Voila, tiny finger-less wheelchair gloves:
(At first I tried having individual holes for each finger, but she's 2.5 and she has tiny fingers that wiggle. A lot. Leaving some of the leather between her middle and ring fingers should help keep them from slipping off, and it was tons easier to get them on her.)
