This instructional painting pattern has 9 pages of directions to guide you with many full-color step-by-step photos. You can accent these with hot-fix rhinestones, or painted dots as you can see in both product photos.
Unfortunately, I don’t have any key charms available, but I do have many different heart charms if you would like to hang those on your ornaments for accents. Here is a link to see all them: https://tolepaintingdesigns.com/decorative-painting-categories/charms-stencils/?s=heart+charm&post_type=product
(This pattern uses DecoArt Americana Multi-Surface Satin and Extreme Sheen Pearl paints.)
