The Shell requires a very stiff serviette. Fold the two edges together
in the centre, lengthways, as shown in fig. 1. Fold in half down the
centre, also lengthways, leaving the edges outside. Then crimp evenly
in the manner shown in fig. 2. Open up the top end, and turn down the
edges each way, as they appear in fig. 3. Keep the lower ends together
like a fan. If well done, it can be balanced on the plate by the ends,
in the manner illustrated by fig. 4.
