Step 1. Buy your materials and fill the ball. The clear balls seen above are at Michaels for $8.49 but are usually on sale for 50% off. You can fill the ball with whatever you like. I use scrap paper and curl it, stickers on paper, ornamental snow, pom poms, beads and ribbon. The list can go on forever.
Step 2. Once you have your ball filled, you can finish it off by decorating the top with glitter, a bow and a string to hang on the tree.
Step 3. Let dry and wrap for someone special.
These ornaments can be as expensive or as inexpensive, as detailed or as simple as you like. Here are a couple pictures of ones that I have made.
