Secure sentimental ornaments to the tree with wire.
"We decorate the tree together as a family with the ornaments that we've collected over the years," says Toronto designer Anne Hepfer. "Each ornament has a special meaning or memory. My most sentimental ornament is a Christopher Radko "Brave Heart" which commemorates September 11, 2001. I was living in New York City on that tragic day. I wire on any breakable ornaments to the tree, that way if a child, pet or person accidentally bumps the tree, we don't have any casualties!"
