If Haley had stackable rings, Lena needed some too. Many people don't realize that, when babies are young, they don't see the full color spectrum for a few months. They like to look at the colors red and black the most because they have the best contrast, making them the most interesting. Luckily, I love fabrics in black and red, so I had a bunch to work with.
I hear that Lena loves the rings and gnaws the living daylights out of them. If anything, they make great teething rings!
