Stones and Roses

What's keeping me up late tonight is thinking about the new bath display and whether I'd like to paint a new backdrop for the tent walls- a stones-and-roses one like I first came to see in the documentary about Guedelon Castle in Burgundy, France. It's a very mid 13th century thing though, so possibly not appropriate for early 14th century displays. Durham Cathedral also has some, pictured here. How late were they used? I simply don't know for sure.

I really think I'd like some. I think they'd really look fantastic with the roses bed hangings I haven't used yet.

I'm idly wondering how to keep my kitty off the paint while it was drying. I feel like I actually have all the right colours of paint already, so I'd just need fabric...
