Make your very own wibbly wobbly Monarch with this jelly mould by artist Lydia Leith. At £10, requiring 2 litres of jelly, it will provide an economical centre-piece to your street party feast. The artist was inspired by a vintage mould of the Queen's head hanging on the wall at her parents' house. She made the moulds, which come in kitsch pink and blue, with special hooks, so they can serve a decorative double purpose when not in use. (www.lydialeith.com)
