My daughter's reply:
"That's funny.

No wallpaper, just a lot of taping, paint and time. Although I almost didn't do it because when I first started Lexi comes in and tells me "Mom. I can do better than that" I told her she had better leave before I popped her with a paint brush. Of course that was before I had started on the horses and all she pretty much saw was tape everywhere. ( if you tape, then you can paint over it and pull it off and it gives you the lines) When I was done she came home from school, ran upstairs and was jumping up and down saying how much she loved it. So "I guess" it was worth all the work.

She just better not out grow horses anytime soon. lol"
