Sorting by Color
To sort Lego pieces by color, you'll need to spread all of your Lego collection on a large table. Counting the different colors tells you how many clear, plastic boxes you need to purchase at a home or craft store. Most shoebox-sized boxes lock tightly, which prevents accidental spilling. Once you've sorted each color into its own box, you can put all of the boxes on a shelving unit for display. Mounting the shelving unit to the floor or wall will prevent tipping.
Shadow Boxes or Aquariums
Many Lego builders, proud of what they've assembled, hate to see their creations taken apart. A storage solution for Legos already put together requires aquarium-sized shadow boxes from a craft store, or plastic or glass aquariums from a pet stores. Several Lego creations should fit into one box or aquarium, or you can display an extra-large model in a single aquarium. Some shadow boxes and aquariums come with lights; while more costly, the lights add an extra decorative element to Lego displays on a book shelf or individual wall shelves.
Kitchen Canisters
Large glass kitchen canisters, found at home supply stores, can display Lego pieces of all sizes. If purchasing storage for a child's Lego collection, plastic canisters serve as a safer option. Some canisters, such as those primarily used for flour or sugar, come with lids that hinge closed for a tight seal, so the Lego pieces won't spill out if a canister tips over. You can separate the Lego bricks by color or leave them mixed together. A plate rail shelf, attached about three-quarters up the wall, keeps the containers beyond a toddler's reach but low enough for older children to access.
