He was made last year a very quick and easy decoration, he was made from a pillow case, in fact you can get two from a pillowcase.
Cut up the middle lengthwise, sew up the new cut sides, you now have two long tube shapes,
fill with stuffing of your choice, I used polystyrene beads, you want it stuffed so it is fairly firm and will stand up. Sew up the bottom then you need to create some shape, divide it roughly into thirds and tie with string, your snowman body has now three sections, decorate one at the end with a face, sew on some buttons, I made a scarf and hat from some bits of an old fleece blanket and decorated with foam snowflakes.
My snowman's face was embroidered on but you can easily do it with felt of fabric shapes and glue them on, or use safety eyes.
