7x7" I've confirmed that Staples does in fact sell staples. Now off to Dicks I go. Wood Sign Sawdust City signs are made from solid knotty pine, so please allow for slight imperfections - as wood is imperfect by its nature - but only adds to the character of the product. It is intended to have a rustic, old look and feel. Expect knots, variance in color, and natural cracks - as well as small edge “dents” or chips.
