Cassidy invented her now patented and commercialized Crayon Holder out of personal necessity. The original Crayon Holder, inspired by the plastic tubes used to keep roses fresh, gave her the tool(s) that she needed to complete a drawing project when her art supplies were down to broken crayons.

The Crayon Holder is a patented device that holds various sized, partial or whole crayons to extend their use and reduce waste. Additionally, the wider circumference of the hard plastic holder makes the coloring and drawing experience more precise and essentially more comfortable. She realized all kids, parents and educators encounter broken crayons and could see the value of her holder. The Crayon Holder is available for sale at bkfk.com and was in the Wal-Mart Back to School Assortment 2005.

Cassidy became a Student Board Member of the National Gallery for Americaʼs Young Inventors.  She obtained a 3-year license agreement to manufacture and sell her product and enjoyed seeing her Crayon Holder on the shelves of Wal-Mart, the worldʼs largest retailer.  Cassidy appeared on various television programs and in newspapers
and magazines.

Cassidy co-founded By Kids For Kids company to encourage young inventors like herself!
