Hello, Ive made this rabbit some years ago, but I didnt remember what pattern I used. I mixed probably some amigurumi head, then I make just balls, and attached all together, and at the end if formed this. I used a fluffy yarn, so the effect will result always cute, even if the shape is not perfect. To make the head, really use any also free amigurumi pattern with a ball shape, the body its another ball (less sfutted so that can be modelled more flat, the ears are just like to start to crochet a rounded ball, but you will stop as soon as you see it start to enroll too much. The outfit was made by inspiring from some patterns here and there (there was a tutorial how to make a suit (no matter the size, I simply use a tiny crochet and I did some trials, but it almost result at first attempt!
Have a good day!
