4. Modern Geometric Painted Wood Shims
Wood shims are inexpensive utility items found in the plumbing or door sections of any hardware store, but their natural wedge shape makes them incredibly versatile for creating geometric, mid-century modern wall art. By arranging these wooden pieces in alternating directions, you can construct a stunning three-dimensional mosaic that plays with light and shadow.
Purchase a pack of wood shims and a sturdy piece of plywood or heavy cardboard to use as your backing board. Before gluing anything down, experiment with different layout patterns, such as a classic herringbone, a chevron, or a radiating sunburst design. To add contrast, stain some of the shims with a warm wood tone, paint others in complementary accent colors, and leave a few raw. Once you have finalized your design and color palette, use strong wood glue or a hot glue gun to secure each shim to the backing board. Frame the finished piece with simple wooden trim to give it a polished, professional look that anchors your bedroom decor.
