You can all laugh when you hear that I had decided to cut the holes myself. After doing 50 of 500 by tracing around a metal circle with an exacto knife, I gave up. Then an idea hit. I searched my entire house for silly putty, and will just hang them right on the front door at eye level. Here's to hoping I'm not a complete idiot, since I imagine 75% of them will fly off in the wind!
lol i did get a little chuckle out of that.
might want to try stapling a rubber band to the top of the door hanger.
it works well and doesn't look to bad.
