I am a stasher that is for sure, not only with sewing and quilting things but Cross Stitch too.
I always think if I don't get it now, it might not be available when I need it. Or I might not have the funds to get it at a later time.
Truthfully, I am very glad that when I was working I "stocked" up on so much. Now when I want to do something, I have most of what I need to do it.
There is nothing wrong with not having a stash, don't let anyone tell you there is.
