I recently bought some plastic bins at the local pharmacy (Longs Drugs, if you’re curious) and found them to be very useful for sorting LEGO parts.
These are sold for organizing small things in a drawer. My mom used to have something kind of like it to sort her silverware when I was a kid (though not the little ones). I’ve put them to use sorting LEGO. I connect them together in a big array on a small table, and then designate each one for a particular type of LEGO part.
It’s usually not possible to have enough bins for every possible category of LEGO part, so I do a multi-stage sort. First I sort into broad categories, which is what you see here, and then I take each category and do a secondary sort, and in some cases even tertiary, to their final categories.
How do you sort LEGO?
