I have a sizable yarn collection.
Not necessarily enough to open my own shop...but enough.
Every trunk, basket, and purse-not-currently-in-use has yarn in it. I also have several (smallish) tubs in my craft room closet.
But it is not my yarn stash that I am most proud of...it is my secret shelf stash of completed projects.
There are times, such as during movies or grad school lectures, when I want to knit but need to not be thinking about my knitting. At these times, I resort to a simple scarf, dishcloth, or coffee cup cozy. As a result, I have a surplus of scarves, dishcloths, and coffee cup cozies. These are all placed on the bottom shelf of the lawyer's bookcase in my bedroom. I have tissue paper affixed to the inside of the glass door so nosy visitors can't see in. This way when a gift giving occasion arises, I can go "shopping" in the stash!
One would think that this would cut down on the yarn and projects I purchase. But that is not the case. The downfall in the system is that if I remember that a gift giving occasion is on the way, I plan a special project and shop for it before I shop the stash.
Still, the stash has gotten me out of more than one jam...like when someone gives me something for Christmas when I hadn't realized we had reached the gift-exchange level in the friendship...
I highly recommend the stash...
...it goes perfectly with my enormous greeting card cache!
