I find it really cute and unique. It's very simple, but yet so adorable. And I think the Swarovski crystal adds an elegant touch to the ornament. It's so good idea to add it there :)
And if you are willing to spend some time making the Christmas tree ornament, please download the pattern there. It's really easy! And it shouldn't be an ornament only. It may be turned to a greeting card, a book mark, or something else... it's up to you :)
Enjoy and happy holidays!
