Several months ago we talked about plastic holders to keep guylines from tangling.
I came across these on the night-ize site. I've ordered two (I was ordering some of the nifty key racks for xmas gifts - check them out. I got one for all my trailer/camper keys) and I'll report back. Heck, if they don't work out I'll use them for their intended purpose: wrapping up my earbuds for travel.
