For something to wind fishing line around, what I found that worked well were in the Sewing/Crafts section at the local Wal-mart, Kmart, etc. They are plastic "bobbins" for sewing machines, made by Singer, I believe, and four of them cost about $1.29. Just ask where the "sewing machine stuff" is. You can easily hold 50-plus feet of fishing line or dental floss on one, and it keeps the line from tangling up with other things in your kit.
