These Baltic birch circles are ideal for many types of crafting. These circles are cut on-site at The WoodSource by our CNC machine. Made of multiple, cross-grain veneers, Baltic Birch plywood is made to be durable. With a grading of BB/BB, this product has a light and uniform colour with allowance for very small sound tight pin knots. Any larger knots are replaced with a small colour/grain-matched veneer patch before gluing.
