Fun with socks

I took a hospital tube sock that I got during one of my recent surgeries…

(Actual socks not shown)

…and filled it with polyester fiber-fill; the same stuff that I use in my knitted creations:

I then tied off the end to make a mouse wrist support:

Naturally, the Cat With No Name wouldn’t leave it alone, so I took the other sock and got out the sewing machine…

…and with some ornamental rope that I had that I was going to use as a sash (but it was too short), I made a hanging cat toy!

I have many odd socks. What else will I come up with?
