Want to add ears to an existing beanie? click here DIY Bunny ear beanie (alter to your desired animal ears)
Don't have a beanie? Don't worry! Take an old sweater and cut it under the armpits. Cut open along one side and then wrap it around your head. Cut it to fit the diameter of your head. Sew it into a tube. Then, put it on and measure to where the top of your head is and mark it. Then, design the ears that you want for your hat on a piece of paper. Cut them out and use as a pattern. Pin pattern to the top of head mark at the edges of your hat. Cut around the ears and across the head measurement between the ears. Sew closed.
