My collection isn't nearly as big as many of yours. But I only just got back into LEGO a few years ago.
I have most of my built sets in several Sterilite stack drawers. While the rest are in LEGO tubs, other plastic containers
or still sealed in there boxes. So far that is working for me at the moment.
What do you do about LEGO boxes? Are they worth keeping? I'm not planning to sell my LEGO anytime soon. I've read that
some people cut out the fronts of there boxes, and toss the rest. Would that be a way to go?
Right now I have boxes stored inside other boxes. It seems like I have more boxes than LEGO.
