I have that problem, too. I can't tell you how many unopened patterns I have. I give a guess and say about 60%,
Recently, I took time to organize them by catagories -- took me a while. But then I found out that some patterns I must really, really like because I had 2 or 3 of the same patterns.
In this economy, I find 'stupid buying' on my part really frustrating.
I bet we are not alone.
