English women and girls are famous for the abuse of hats at celebrations. I saw this strange habit at the Luca’s marriage too. If lots of hats are around in English houses, you can find hat boxes too. So, if you are a real wargamer, you can sacrifice a hat box to built a circular arena. The only thing to do is to cut the height of the “walls” to a more proportioned dimension. Some paint work, some sand and grass for the terrain, some details added as doors and gratings, and you have got your arena. Look more for this one here.
