LOL I know exactly what you mean! Today I found out that I have are two 50 gallon totes worth of left over fabric.
I don't keep everything either. If there isn't enough space on the fabric to do anything applique wise, or if the fabric is less than 1/2" it gets tossed.
It's been awhile since I've organized everything. I'm gonna have to get on that soon. My quilting table is getting ran over with new designs and fabric. Not to mention that my thread stash is starting to take a life of it's own.
I've been so caught up in making quilting blocks, designs, and wall hangings lately that organizing has been left to the back burner.
School for the kiddos starts in 3 weeks and will give me a lot more time to get it done. I just hold the stash survives that long to let me sort it out. :P
