My Tardis Door! In progress!
Here's what I did, with some help from my sister and dad.
I got 4 pieces of wood and cut them to size. Then I nailed them to the door. (So the original door panels are under the pieces of wood.)
Then, I made rails and stiles. I glued them together with biscuits, and then painted them.
I nailed the rails and stiles to the door.
And that's about it, so far.
