Hairpin legs are really cool to use in DIY projects. They make any table or desk you make looks like it was made in mid-20th century. For example, here is a DIY coffee table made of a sheet of polar wood, a can of stain and a set of hairpin legs. The project is really simple, because all you need to do is to screw the legs to the tabletop and stain this tabletop. Although the result looks great, right?
