So Martha isn't known for her mod decorating tastes. The woman knows how to decorate a tree and the advice is good regardless of what the ornaments look like.

Our Secrets for Trimming the Tree
There's no wrong way to decorate a tree, but if you want to emulate our style, follow these steps.
1. Place tree stand in a watertight planter (ours measures 18 inches square) to yield a more tailored look than a tree skirt—and create extra room for presents.
2. String up the lights first, running them around individual branches to create a sense of depth.
3. Lay out ornaments, and consider a palette. Hang dominant colors to establish a rhythm, and then intersperse them with accents in other hues.
4. Use simple ornaments to create a backdrop for more ornate antiques as well as homemade, sentimental favorites.
5. Take a step back while decorating to see which areas need filling. Hang ornaments inside the tree—not just near its edges—for added dimension, and don't neglect the back of the tree.
6. Hang fragile ornaments near the top, where they will be less likely to get knocked off by pets and passersby.
7. Emphasize the vertical shape of the tree by hanging long, dangling ornaments—for example, icicles and teardrops. Suspend icicles at branch ends so that they look as they do in nature.
8. Keep lightweight clip-on ornaments (such as birds) on hand; they're useful fillers at branch ends.
9. Turn the lights off (or down if you are using a dimmer switch) when photographing, because excessive glare will make the tree look flat.
10. When taking down ornaments, organize them by color in boxes. Keep them in a cool, dry location, such as on the top shelf of a spare closet.
