We have a few block play areas in our house. We love to build with blocks. We have wooden blocks, baby blocks, Lego's, cardboard blocks, jumbo blocks, and I am sure many more around. This is the block set they fight over most.
My parents made this for my son a few years ago. They have a wood shop and the logs are cut very smooth. We once had a lot more blocks but My son uses them in his room for his toy men to fight on. We got them at first for him to paint on. I wanted them so my son could make little wall decorations. He did paint up a bunch. They have a lot more fun building with them. When they build they can take down and build again. When they paint them they don't have much interest in them afterward.
