If you make them 'glove shaped' by drawing round their hands with thumb and little finger stretched out they will be able to make their own and will be so proud of them.

They will probably be able to sew them - I've made puppet this way with my class of infants - but if not a line of fabric glue works well. Dress them with cut out fabric glued on and wool hair.

For other models I've used polystyrene packaging - either find some from things like TW's or washing machines or stick it together with glue and then cut it to the shape you want. You can papier mache over them if you want. To re-use the shapes don't forget to put in a lining layer!

Hope it helps
