Thanks to reader Rebecca, who sent a link to the first fabric here, I’ve just discovered Spoonflower, which lets anyone create their own custom fabrics.
A TARDIS toile:
Created by Shannon Schenck, and available for purchase at Spoonflower. (Rebecca and I agree that we can’t figure out what sort of Doctor Who-ish thing is happening in the bottom right scene. The other three all have DW elements, so it seems likely that this one should too. Perhaps the image is simply too small for us to see.)
Other Doctor Who fan-made fabrics I found on Spoonflower:
“The Untempered Schism” by Sharon Turner:
“Modern Gallifreyan by Studio Fibonacci:
There are many others to explore.
(If you stumble across a cool Doctor Who thing, feel free to email me with a link.)
