craftgrrl | You're Making a What??

Hi everyone, I just joined. I'm a beginning crochet fiend, and I made some simple gifts this year like bags and scarves. But tonight I have a challenge. I know this really cool girl who lost the end of her finger, up to the first joint, to an evil car. So when the weather gets cold, it really bothers her. So her sister came up with the idea for what we are calling a "nubbin cover". I think I can just make a very small version of one of my purses and the idea is that it will be like one glove finger.

I'm all ears if anyone has any ideas. I'll post pics if it looks good, I plan to make a few different colors tonight.
