A while back I made a Dr Who hoodie for one of my friends, and fully intended to put the stencil up. I recently got reminded, and here it is!
I scaled it so it fit an A4 piece of paper, and my stenciling technique can be found here: [link]
Just cut out the black bits and you're good to go.
You could take the easy way out though, and just print it on to an A4 sticker or something. I should point out that there are some details present on the stencil that were too finickey for me to do - the writing on the police box, and a few elements at the top left of the stencil. If you do use my stencil I hope you post a pic up on devart and send me the link. And if you figure out how to incorporate the writing, I'd love to know how
ETA: I know this sounds like a crazy request, but if you do use this stencil, could you please credit me? Nothing absurd, but a link in your description would be nice. I've seen a few people who have used this stencil taking credit for the design
of it in the comments section on their deviation rather than the application
of it. I'm not asking for much, just a link back
