Rows of cotton sash cord update a plain, painted plywood board. The look is similar to embroidery or cross-stitch, yet isn't overly difficult. We love this design for a modern bedroom where sharp lines and clean designs are at the forefront. Plus, it's an inexpensive headboard to make from a large wood board. Get the look by drilling holes in the plywood, then weaving cord through. To hang the headboard, attach D-rings to the frame and mount on screws.
