I made a few of these 5-minute ornaments today.
Then I made a pom-pom. For those who don't know how that works, I took a photo. I used my bow-maker to hold the yarn. Wrapped it around 50 times, and then tied a doubled over piece of crochet thread tightly around the center (I left the loop on the crochet thread long and used it to hang it on the branch). Then I cut the ends, so there weren't any loops on the frilly yarn, fluffed (I recommend doing this outside, it was really messy!)
They show up so well on the tree and were so easy and my little girly-girl loves it!
