Then we bought five bags of these wood
circles (“discs”) from Hobby Lobby.
We just started laying the discs out exactly how we wanted it. We filled the entire thing with as many pieces as we could and it took both of us just moving the pieces around like a puzzle. We used Wood Glue and lifted each piece from its place and put a pretty BIG daub of glue on the back and pushed it right back in place.
We kept going until they were all glued down. It was that simple.
