We have walls in place and they're red!
Using the heavy duty construction tool (aka white glue) walls were pretty securely put into place. (I was impressed with how solid they are once they dry).
Next post will have more pictures and more details.
I will post the "stages" as we put this together.
BTW - did I mention that my daughter is already googling how to make the proper scale tack (read bridle and saddle) for her horses.
We had to tell her to be gentle with her parents or none of it may ever get done. LOL
