I bought these shelves because they were such a great deal. I don't have the GOML dolls, and will not be getting them either. But, I did try out the 18" dolls on the shelves, and they look pretty good IMO!

The 6" doll stand base over hangs a little on the steps, but not too bad. I'm thinking of ordering a few more for the future, you can't beat it for $8!
