I used the following yarns on a 3 mm (US 2/C ) hook, so the entire toy turns out at a size of 47 cm (18 inch). For fur Hayfield Baby Chunky Shade 0407 (70% Acrylic, 30% Nylon). For legs Drops Karisma-Forest Green Shade 47 (100% Wool). And for body you can use any dark shade yarn, I used dark purple.
