I'm a bit OCD. I bet that doesn't surprise some people. I save the empty spools when I use all the thread up. I used up 23 spools of thread last year, BTW. I also found myself saving my thread snips. Not intentionally, I swear! I just never emptied my little bin I keep by my sewing machine. Here is a photo of last year's batch. I actually had a hard time getting it out of the bin.
