Draw the shape of a spider onto a piece of thin cardboard then cut it out. Trace around that shape onto a piece of black cardboard with a white pen and cut it out. With the white pen, draw a spider’s web onto a larger square of black cardboard and cut around the edges. Make a red paper spring by attaching strips of red paper to each other at right angles then folding the strips over each other alternately. Attach the spring to the centre of the web; attach the spider to the other end of the spring. Write party details on the back of the web.
