This is a beanie/scarf thingy I knitted for my daughter Cassie several years ago. Knitted from a variety of different yarns, to my own design.
I think I made the pom-pom first, in order to ensure I had enough yarn to do this, and also wound off enough yarn for the tassels on the ends of the scarves at the start of the project. Then the beanie was knitted from the crown down to the rim, cast off except for the stitches at the sides where the scarf sections were to start, then the scarves knitted down to the ends. This meant I could just knit away happily until all the yarns were used up completely; ta-dah! zero waste!
