Crutches covers

[lady-amorika.livejournal.com]

Hey grrls,
Sorry that this is text only, but I will post pics of finished products :)
I just recently scraped myself up pretty bad, and I'm on crutches. I own my own pair of crutches, but they desperately need covers for the armpit/hand spots. They are in excellent shape, I bought them new, but as most of your probably know, that padding smells terrible. I am looking to make covers, would anyone happen to have a tutorial that they know of, or any hints/tips? These covers can be mostly permanent or whatever, but it'd be nice to have an outer cover that I could wash.
I have a sewing machine, but I don't think I can use it because it's my left ankle and my right knee, so I don't think I could accurately use the pedal.
I'll be eternally greatful for any advice/hints/tips/tutorials.
Thanks everyone!

Edit: I don't mind hand sewing...heck, what else am I going to do? Hehehe
