First, take your smaller ornaments and remove the silver top.
Then use the knife and scissors to carefully cut off the extra top part. This can take a bit of time so be patient and very careful! However, perfection isn't necessary. It will be glued to the bigger ornament anyway and hidden with the pom-poms.
When you have both small ornaments ready, use the hot glue gun to add them to the bigger ornament in a Mickey Mouse shape. Make sure to hold each one for a few seconds when you first glue it on to ensure it sticks and the glue dries.
Now that you've got the Mickey shape, take the Pom Poms and start adding them. Work in small sections and work fast. I used some old tweezers to help me pick up the poms and place them on the ornament. It protected my fingers from the glue and I could pick up the poms a lot quicker.
Continue working your way around the ornament mixing the sizes of Pom Poms as you wish. I tried to add the bigger ones to the bottom and add smaller ones to fill in empty spots. You can do it however you like best until it's all filled in.
When you completely fill the entire ornament, add any extras you'd like. I glued two small craft bows and added a piece of ribbon for a special touch. I absolutely love how this craft turned out and I cannot wait to hang this on our Christmas tree!
