More about Lego in our lives. Our boys have lots of special Lego set that they got for Christmas from their grandparents. These ones they like to keep separate and play with on their own in their rooms. But they were often falling apart, and we couldn't fix them, and the manuals were all over the house. So we got an old binder, filled it with page protectors, and put ALL the Lego manuals in it. This stays on a shelf in the cupboard, and now any time we need to do repairs, the manual is right there.
I put all the manuals from one set into one pocket (some sets have two or three different booklets). I wrote the name on the corner, as well as the date we got it.
