Cut two equilateral triangles from your black or brown felt with 7.5 cm (3 inch) sides. Cut two triangles from your pink felt with 6.2 cm (2 1/2 inch) sides.
Wrap yarn around your hand about 10 times. Carefully slide the wrapped yarn off of your hand, keep the shape of the wrapped yarn so you can clearly find the centre of the yarn. Tie a short piece of yarn through the centre of the wrapped yarn to hold it together. Snip the yarn opposite from where it is tied. This will be the hair for the horse headband.
Wrap yarn around a large book from top to bottom about 10 times. Wrap the yarn more times for a thicker tail if you wish. Tie a short length of yarn around the wrapped yarn at the top of the book to hold the strands of yarn together. Snip the yarn at the bottom of the book to create the horse tail.
Hot glue the pink felt triangles inside the brown or black felt triangles so that the bottom edge of the pink triangles line up with the bottom of the other triangles to create the horse ears. Hot glue the ears to the blank headband. Hot glue the horses hair to the headband between the ears.
Attach the horse tail to a large safety pin by slipping the pin through the piece of yarn tied to hold the tail together. Use the pin to attach the tail to the bottom of your shirt or your trousers.
Dress in an all black or all brown outfit to complete your horse ensemble.
