I've learned that trees look best if most of the ornaments look like they are "growing" off the branches rather than hanging off them. Meaning, they are placed right under the branch with a wire. When I was decorating my tree this year I had been to the store multiple times already and always forgot to get wire. I was over it and was thinking if I had anything at home that would work. Bobby pins popped into my mind and I knew it was a genius thought and surprised myself! HA!
Now this doesn't work for all ornaments. Only ones that are pretty light weight and not terribly large. The video below shows exactly how I did it!
