I’m so fascinated with this: Dutch designer Wendy Plomp used flattened cardboard boxes and printed carpet patterns on them. 
Would be perfect for a big lofty studio or in an office/workshop area… Also great for a fun outdoor mat. 
Could be a fun DIY project too! (saw it via the latest British Elle Decoration) It’s all so… brilliant really… Cardboard is so happy mundane.
