I'm not allowing myself a quilting stash because I know I will be the same.
I used to to do beading and bought every single colour of Swarovski I could find and then refused to use them as that colour would be gone from my set. I loved just admiring the pretty colours and still have them, but it eventually spoilt the hobby for me and I'm determined not to do that with quilting. I come on here to admire pics of everyone else's stash instead, I could look at pics of peoples stashes all day long and not get bored!
