Ok, this is a little more random, but a few years ago I was looking for a new air freshener for my car. I went to Bath & Body Works to get a refillable one, but they had no cute sparkly holders at the time! They did have this heart and paws one, though, so I added my own glitter. I put pink glitter on the paws and pink paint with iridescent rainbow glitter on the heart. The paint didn’t stick very well to the heart and required many layers and a lot of patience. At least it seems to have held up fine once it dried. It probably would have been easier to use nail polish (which I’ve done before on an old cell phone, back in the days of flip phones). Crystals would have been fun, too.
By the way, my favorite B&BW car scent is Watermelon Lemonade. It smells like bubblegum!
