This is a cute little melt-and-pour project that I'm experimenting with today using Sheer Freesia fragrance oil (new!). I used a dropper to free-hand a flower in the bottom of my oval mold and then filled the rest with opalescent green mica. The pink flower petals came out a bit faint, so I did a layer on the surface to pop out the color. The trick is to use very cool soap so that it stays in place where you put it.
Don't worry if free-hand designs aren't your thing-- roughness adds to the charm!
