Looking for the artwork of the St. John Ambulance sign on the door was a little tricky. Secondly, the logo has changed over the years, and from this screenshot, there was nothing really quite like it. So I started creating one in Adobe Illustrator that I could use since the screenshot lacked the fine detail I needed.
Then we get the "blessed" Christmas special, and my world just got a LOT easier.
The TARDIS was using the newer logo and I was able to find one in High-Res online, and it was easy enough to make a vector image of it in Illustrator and make a vinyl cut from it.
What we have is two templates. The first is the black circle that is painted first. The second is the mask template for the white paint. The face detail was too small to keep, so I will do that part by hand later.
I used the masking tape as a guide when lining up the vinyl. Once it was laid on the door, I masked around it to keep from the over spray. ONE WORD ABOUT PAINT... Cheap was NOT a good idea here. I had to REDO this door a couple of times for different problems I had. Since the paint was not drying quickly, it would want to lift the vinyl and bleed through. When I did the white paint, it was very obviously NOT good.
Since I was using enamel based paint, I decided to buy both black and white "quick dry" enamel paint from Lowe's. This worked! Peeling up the vinyl left nice crisp lines.
Here is the final sign on the door. The face detail was added with a fine tipped Sharpie.
It isn't perfectly the same, but it is close enough. I am glad I didn't notice the difference before I painted it, or I would have spent hours and hours trying to make it "perfect".
