It was created by a St Louis ceramicist who calls herself "idahostudios" on flickr and has an amazing sense of color. And because she did it on the cheap we thought it would be a great idea for SF readers struggling with the epic long hallways so common in our Victorian flats. So we asked her how she made it and she said...I used to work at an architectural/interiors firm, and had access to extra samples, so that's where they came from- already cut- I didn't cut them. Put them together with duct tape on the back and voila. No adhesive or rubber coating, it just seemed to stay put for the most part.
