Over the course of a month I slowly pieced this together. I made a few mistakes and redid a few things, but overall, it came out looking really nice and the person I made it for was in love with it. This is for personal use only. Enjoy!
I used: Cardboard, White Posterboard (or cardstock), Hot Glue Gun, Blue/Silver/Black Acrylic Paint, Glue Stick, Thin Wire, Cereal Box, Semi-clear Plastic Sheeting, Varnish, Straight Edge Blade, Ruler, My Printer, Scissors, and lots of sweat and tears
I was inspired by "TARDIS Chocolate/Trinket Box" by ~aria-arissa [link]
Images of Doctor Who characters were created by ~Hawkstone [link] and are available for sale as magnets on Hawkstone's site.
Doctor Who shapes were created by *Girl-on-the-Moon [link]
EDIT: I have been pointed out an error made in my haste (so embarrassing): "~Mordrogyn Cool but you realize you have too many panels on the sides right?" When making yours, you might want to take Mordrogyn's advice.
I featured your lovely deviation in my Extra feature journal: Doctor Who
I'm doing it now, actually, almost finished - the only thing left is the insides
Look awesome!
