1.5 Ball of yellow for the body, less than one ball of orange
Embroidery or decoration thread 8 white and suitable hook (1.75 for me)
1 large pompom or acrylic thread for the tail and a wick and brush the threads or a little felted or carded wool: in yellow or orange shades

I put iron-on eyes and mouths but you can put 10mm safety eyes or make them out of felt or embroider them
(black and pink felt) suitable glue
