All of our boards are handmade with a solid oak frame and soft felt of the highest quality. (We know they're durable because they've survived the 6 little curious hands - and, let's face it, the one clumsy mom - we have around this home!) Every board comes with a set of plastic notched letters that fit perfectly and easily into the slots on your board. Any size of letter set will fit on any size of board; mixing and matching sizes creates an awesome look we know you will love! Our letter boards come ready to hang with mounting hardware on the back. We stand behind our product, and we know you will be as happy with our boards as we are.
