The idea for this was taken from http://blog.betzwhite.com/2009/12/felt-ogee-ornament-tutorial.html. She did her's with felt. Well felt is not my medium of choice, but I loved the look and did mine with green plastic from a Mountain dew 2 litter bottle. You can get 2 six inch squares from 1 bottle. I did cut/melt mine with a soldering iron but a pair of scissors and small hole punch would work. I used brads to attach it, though next time I might use something different, not sure if I like the fact that I can see the prongs. Might use some brass beads.
My other regret is that it did not fit in my light box, the picture does not show it in the best light.
