i'm obsessed with these simple wood-burnt rings! i bought these little wooden circles at the craft store. an entire bag of them... so if i messed up, it didn't matter! don't have a wood burner? try carving. then use a small paintbrush to apply stain where you carved.
my friend said she would paint them, so that's an idea too. i personally love the simple & natural look, but i may want to add some color someday.
