Frances, Exactly the way I feel! It's like you read my mind.
We don't have a real LYS in our community, but when I do go to a town that has a LYS, I always buy something! Sometimes it's only a skein or two, but I always find something. And amazingly, as I'm looking over the yarn in these stores, I can see the project that the yarn should become... the light bulb keeps going on... over and over again.
Frances, no matter how many lifetimes I live I will never be able to knit my entire stash because I just keep buying more.
Susan, my DH tells me I should open a lending library!
