Knowing the overlap between SPWS fans and Doctor Who fans is, to put it midly, healthy- I knew you'd enjoy this Tardis pattern I submitted to Spoonflower. Spoonflower is a print on demand site for fabric- upload your designs and order them with a choice of several fabrics.
If anyone winds up making a project with this, I'd love to see it! Each little Tardis Is a bit over an inch wide, and one every 8 square inches has the door slightly ajar. It's up to you to make your project bigger on the inside. Or time travel- though let me know if you figure that one out.
