Love the southwestern theme. I especially like the idea of the carpet runner on the ceiling. Be careful where you sit with those horns.
We are doing a bit southwestern in the
Campster. We have an old queen set of matching sheets, cases, and bedspread in a southwestern pattern. My wife is going to cut the fitted bottom and the spread to use as covers for the benches, then use the flat sheet for curtains.
I think extending the theme to your curtains would look nice.
Have fun.
