ahem. well i found another use for them!
sparkly 'gemstone' jar lid ornaments
i made these together with my 4 year old daughter & she absolutely loved it! they were super easy, not very messy & there's really no wrong way to do it [always a plus with kiddo crafting!]. since she loves 'my little pony' she called these gemstone ornaments & i thought that was pretty cute. she was pretty proud of herself... waiting to let them dry to put them on the tree was the hardest part! this one was a pinterest project that i snapped right up because i knew my big girl would love them.
-prime your lids if they're not already a pretty metallic color, or if you want to cover up any writing
-hot glue a loop of twine inside the circle. if you forget, you can glue them to the backs & cover it with a felt circle. i may or may not have had to do that on 2 or 3 of them...
