I put her on the floor of a large plastic doll house. My plan was to put it on a big wooden board and put these wheels on it. For various reasons this did not work. So plan B (which didn't exist when the project started) was to glue the wheels on. The flat metal surface on top of each wheel lends itself well to secure attachment with Stonebond (two-part superglue). Now kids can move the dollhouse by themselves. I have 4 wheels left for the fabric toy basket/bench. lower and inner cardboard layer. But I'm still trying to figure out how to install them. Probably put a thin piece of wood in there and screw the fabric to it. In any case, they are big. And they are strong and durable. If I need to make other items moveable, I'll pick them up again.
