A well-decorated tree mixes a few ornament types. Most people start with a large set of shatterproof ornaments to fill the tree in one color scheme, then add a handful of glass ornaments as statement pieces where they are safe from pets and small children.
Personalized ornaments mark a first Christmas, a new home or a family member's name, and they become keepsakes you bring out every year. Finish the top of the tree with a star, angel or bow topper that fits your tree's height and tip.
As a rough guide, a 7 ft tree holds about 60 to 100 ornaments depending on size and how full you like it. Mix three sizes: large ornaments deep in the branches, medium ones in the middle and small ones near the tips and top. Hang lights first, then ornaments, then the topper.
When the season ends, keep everything safe in a divided ornament storage box.
