I like to hide my yarn behind my chair in the living room. Hide being a figurative word, because everyone knows it's back there. Still, we'll go with hide.
So, the yarn is in various states of hidden. Some is hidden in a plastic two drawer storage unit, some in last year's Boy Scout Popcorn tins (another reason to support the cub scouts! yarn storage containers!)and various bags. I have even tastefully hidden fluff (aka roving and spinning supplies) in metal milk box.
Even with all this awesome storage yarn manages to sneak out of it's confines and the cat makes nests out of it. Which freaks me out, because it smells like barf behind the chair. I'm starting to become concerned that a cold homeless person has sought refuge in the warmth of my stash, or the cat died back there. Either way, it's something bad, and smelly, and I'm afraid to look.
