Boxes made shelves/cubbies. Smaller ones than some of the others, more for display. DIY shelves - love the pop of color and pattern on the backs of these! They look like serving trays turned into shelves
Use Old Crates and Drawers as shadow boxes. I love this. Went through my Dads barn and found some old crates and boxes that my Grandfather made to store nuts, bolts, screws, etc. I have them hanging on my wall now.
