I've got a large dresser next to my bed that really needs something on top. Often it has a vase of real flowers but I'm fed up with retrieving dropped petals etc. I've seen a lovely artificial display in a glass vase in John Lewis, but I've never been sure about artificial flowers. Trauma of one too many garish eighties bridesmaids bouquets I think. Can they work in a cosy, cottage interior? What alternatives might work?
