Paging #Lego experts. How do you organise and sort bricks? This *feels* like there should be an optimal, systematic method for finding what you need.

We've got about 45 years worth of Lego and are trying to sort, especially for ones where we have the instruction booklets. Some sets are partially intact from kiddo's shelf, but we will need to ensure all parts are there before we can move these on.

E.g. purely by colour? Types e.g. plates and standard blocks, and then colour / size for all the random tiny pieces?
