An adult (or older child) draws a large simple pumpkin shape in thick black marker on the white card, filling most of the page. Add a short stalk at the top and three curved lines down the pumpkin body for the segments. Draw a simple triangular jack-o-lantern face in the centre.
Tear the orange tissue into rough strips, each about 2 cm wide. Tearing is better than cutting here: the ragged edges create a more interesting texture.
Brush thinned PVA glue over one section of the pumpkin at a time. Press orange tissue strips onto the wet glue, overlapping the edges. Work from the outside of the pumpkin inward, stopping at the face shapes so the black outline shows through.
Tear small pieces of green tissue for the stalk and add a few curling green strips around the top of the pumpkin for vines.
Leave to dry for five minutes. The tissue darkens slightly as it dries and the surface becomes smooth and almost translucent, which is exactly right.
