Cecile, the window cat is an adorable toy, knitted in the rounds, with I-cord as a tail and small ears. Use any medium weight yarn in your color of choice.
Yarn: Cascade 220 Superwash in color of your choice. Or Dream in Color Classy, or any worsted weight yarn. About 100 - 150 yards / 91 - 137 meters total. About 5 yards / 4.5 meters black
Notions: Yarn needle, scissors, stitch marker, polyester fiberfill (1 small bag), a smaller smooth rock for weight up to 3” / 8 cm in diameter (optional). If planning to make this cat as a gift for a small child, I would suggest to skip the rock for safety reason.
