This is the side of the door you all know by now;)(just to recall ;))
For the other side of the door, here is what I used:
(And a bit of glue of course;)) The cardboard is thiner this time so it was easy to cut:) The pattern just jumped out of my head straight on the paper ;) Also easy to cut - as I am lazy - remember?;) I cut this pattern four times and glued two together so that the hinges were a bit thicker. Except for the big parts you see above I cut also four smaller/narrower parts just to make door looking more interesting. The narrow parts are supposed to resemble the snakes :) The nails in their heads are supposed to be their eyes and are made of the smallest black Svarovski gems I could find - I used them also to cover the holes after the original hinges ;) And here you can see the floor right in front of the door.
To finish the door I need just one more thing...
