Try this if you're changing the theme of your tree this year, and find yourself with some spare ornaments. You can attach ornaments to metal forms by looping floral wire through each ornament's hanging caps. Glass balls are light enough to attach to foam wreath forms with glue, too.
The Etsy artist behind the creation shown here used a variety of ornament textures—from shiny to sparkly to matte—to create this look. Want the look without the work? Order a custom, handmade version from the artist.
