I didn't just wake up this morning and was suddenly able to draw, unfortunately, so I printed out a dove template from the internet and drew two outlines on the door. I really must remember to rub out the pencil marks before I take photos.
To achieve this look, I cut some striped tape into thin strips and criss-crossed them. I soon got tired of that, so I cheated and cut the lime tape and spotted tape to size for the rest.
Time taken: 1 hour to make one
Result: Let there be peace on earth one washi dove at a time.
