Check out my Spoonflower shop for printed fabric (and wallpaper) in medieval, Renaissance, or “Creatively Anachronistic” patterns. All historical patterns are based on actual medieval or Renaissance textiles.
If you’re a SCAdian with DIY inclinations, I also have cut-and-sew panels for making mug rugs (like a mini placemat/oversized coaster) or banners with populace badge heraldry for more than 300 groups, plus officer and peerage badges. (Mug rugs are great for largesse, by the way.)
…And if Art Nouveau, Arts & Crafts, or some other style from after the Renaissance but before 1920 is more your thing, check out my other Spoonflower shop, Red Tansy 2.
