The great Lego sort of 2011...
I finally let my little OCD tendencies take over for a week and sorted all of our lego BY PIECE TYPE. The boys are allowed to get out lego, but not put it back yet. ;) I did spend about $85 on the bins/cases, because I wanted it all to match and be pretty, but I am happy. And building a kit with my 6 yr old took about 15 minutes instead of 3 days (finding pieces used to take so long that I'd quit doing lego with him).
Anyway, posting per request, not because I'm all that proud to be so obsessive... :)
