A kaleidocycle is a fun toy that you can keep turning inside out in the same direction over and over again, watching it change colour as you do so. This crocheted version is cuddly and soft and drool-resistant. The perfect gift for your favourite geekling!

Materials: Preferably worsted yarn, less than one ball each of four separate colours for the sides, less than a ball of contrast yarn for seaming, and stuffing.
