Ralphie the Christmas Bunny is crocheted in the round. The doll body is crocheted first and then the bunny suit is crocheted to fit loosely onto the doll. The yarn used is mostly Hobbii Rainbow 8/4 but it is written for ANY size yarn. The doll is crocheted in one piece from top to bottom. Arms and the soles of the feet are crocheted and sewed on separately. Hooks used for this yarn were B and C. If you choose to use worsted weight yarn then you should use a D and E hook.
