Your hooks and hangers don't have to be plain and boring, they can flutter across your wall like butterflies on a spring morning.
Use them to hang hats, bags, scarves or in the bathroom to hold a towel. Each kid could have their own color (red, orange, yellow or silver) or mix and match them across your wall. The hooks are made of metal and measure about 4.3" both high and wide. Unfortunately, they're surprisingly expensive at $23 each (here). (Have you found any similar that costs less?)
In case you're wondering, we weren't sure what to call a group of butterflies so we checked with the North American Butterfly Association and learned that there is no official designation. But here are some suggestions they've culled from their members: a swish of butterflies, a tango of butterflies, a ballet of butterflies, a spray of butterflies. See more suggestions here.
