Came up with this idea (probably not original, but I haven't seen it yet).
Does your yarn drawer/box look like this?
This was just a few I laid out to get a pic.
Well put the two together and you have a great yarn keeper.
I rolled the sock down and slipped it over the skein of yarn. Make sure the end where the start of the yarn comes is at the open end of sock. Then you can just use it right from the sock. no mess.
