Quick pics: some shots of our front window - not very good because of the glare. Well actually more like an almost-mirror-like reflection. I tried to do an arch to frame our Christmas tree when the blinds are up, and I used white copier paper and light blue translucent paper. I pretty much winged it, so some of the first ones are square.
Here are some close-ups. Some are folded so there are 6 prongs, some are 8. I put the tape on the holes and not on the outer edges so they would look like they were floating.
Hope this inspires you to do something crafty for your Christmas decorations!
