Wrap even sections of green and black wool alternately around the polystyrene wreath. After each section or length of wool/yarn has been wrapped around secure, first by tying a knot and then by placing a pearl head pin through the wool/yarn and into the polystyrene wreath.
Continue with this method until the entire wreath is covered.
To make the bunting, cut four equal size triangles from kraft card, using a hole punch along the top of the triangle to punch two holes.
Write out the ‘Boo!’ greeting using a black felt tip pen, apply googly eyes to the bottom of the ‘o’ letters.
Thread a 30 centimetre length of twine through the holes and attach to the back of the wreath using pearl head pins.
To hang the wreath, plait a one metre length of the black and green wool and the twine, knot at each end, fold in half and secure each end with a pearl head pin on the back of the wreath.
