Oh yeah... The glory of sorting. During this wonderfully (and unusually HOT) Summer of 09 here in high-tax Sweden, guess what I did? Was I outside on the beach? Was I taking walks in the park? NO! I was sorting 30,000 pieces of LEGO right from scratch. The scary part is that I (with the help of Mom, naturally), was able to do it within a two-week period.
I currently hold 217 boxes of sorted LEGO, all of which are sorted; be it by theme or piece. I also have six boxes of those cubicle suitcase things. For the fun facts, more than 3000 SEK (roughly more than $300) were spent on some of the highest quality storage boxes I have ever seen. Yep... Well, at least I didn't have to pay for it. Would have ruined my LEGO shopping list for the next year!
The pain of sorting though, is that it requires a HUGE amount of discipline. The MOCs and purchases add up extremely quickly. At the moment I'm sitting next to about 1000 pieces of LEGO that has to be resorted. Ughh.
