LOL... have fun!

First things first: replace all the glass balls with the plastic ones! I did that last year, and NOBODY ever guessed they were plastic! When I put the balls on, I also pinched the wire hanger tight so the balls wouldn't get knocked off as often (they still got quite a few off, but they didn't break!

I also tied each strand of beads on with wire. So each time a bead dripped over the top of a branch, I put a little wire twist to secure it to the branch, so that little kitty paws couldn't take it off. You can use the ornament hangers, twist ties, pipe cleaners, etc.
