The spider is made from pipe cleaners and furry fabric. You twist four pipe cleaners in the middle, wrap a strip of fur around, then use a long piece of cotton to wind all round the body and in between the legs to keep everything in place. Then you use a darning needle to thread elastic through the top layer of fur, and finish off with googley eyes.
The bat is cut out of black card, with some strips of netting stapled on top. Again we used a darning needle to thread the elastic through. You can't see in this picture, but the end of the elastic is tied to a stick so you can bounce and fly the bat around. Cool.
The pumpkin is just bits of torn up orange tissue paper glued onto gold card. We sprinkled some green glitter on top too so it catches the light. We were supposed to make it into a mask but didn't quite get round to that (someone lost interest and started running amok with all the stuffed toys. It wasn't me).
