Got a ponytail? Peekaboos hats are designed to let your hair hang out. These adorable knit hats feature hidden holes in the back for your ponytail to peek right through so you can keep your head warm and your hair pretty.

What started as a knitting mishap became a business idea for college student Danica Lause. Knit one, purl two...oops...she dropped a few stitches and ended up with a hole. Instead of throwing the hat away, she found a way to put it to good use. To her delight, she received lots of compliments and a new product was born.

Today, there are no mistakes, just machine washable, hypoallergenic hats with patent pending, hidden openings for both high and low ponytails. Once you wear one, you'll be hooked.
