An arena from the miniature wargame past. This thing was created a lot of years ago but it is bright with its simplicity. First, take a biscuit tin, then decorate it with some shaped and coloured card using some glue, giving to the box an arena appearance. On the lid there is the place for a rule summary. Magnetised miniatures can fight in the arena even in travel. Simple. Fast. Easy to storage. And you can eat biscuits before making it! More information here.

Another version of the same idea. This one is a step by step guide to your tin arena. Designed for D&D miniatures and with a medieval feel. You can find downloadable decorative elements for this arena on the dedicated web article.
