Living in a small house, I have to find storage wherever I can. There is one built in shelf in my hall that I use for storage. I have got all kinds of goodies hiding in those gray Ikea Kvarnvik boxes: wrapping paper, ribbon .
Using IKEA boxes and thin Lego board that's primarily used for the smaller Legos. Tip Duplo Legos fit the small Lego board. Tip small Legos fit on the Duplo Legos, when making the transition from Duplo to smaller Legos.
