Hanging Calamityware is an excellent way to enhance your domicile. I use invisible plate hangers that glue to the back of the plate and can be removed later by soaking. These big yellow stickers are completely invisible behind the plate. I use the 100mm size. You could probably build your own with duct tape if you prefer DIY.
I’d love to, but the numbers don’t work. I’d need a lot more European sponsors to justify the expense of shipping, inspecting, packaging, stocking, fulfilling, and tracking in two different places.
