This is a link to Bonnie's intro to the mystery. She explains her color inspiration. You have to scroll through several scenic photos, a photo of the paint chips, a photo of the 3-in-1 color tool, and then come the photos of Bonnie's fabrics. It's easy to miss the yardage amounts, as they are very inconspicuously typed below the fabric photos.
