Becca, have you considered making a PVC niddy noddy? I made mine for under $3...and it's soooo nice to have. Beats winding off onto legs/found objects.
I used 3/4" PVC for mine, 'cause I heard it was sturdier. My center piece is 13", and the smaller pieces are 3", but otherwise it's just like this one: http://www.doctordirt.com/blog/niddy.html
