A tradition in part of the US called a 'cake pull' sees charms hidden in a wedding cake with satin ribbons attached, which female wedding guests all pull together. Each one says something about their future, eg. marriage, children, wealth or travel. (The poor thimble once again predicts a future alone.)
This is another tradition that would provide a bit of fun at a wedding, bridal shower, hens night or kitchen tea. What warm-blooded female doesn't harbour some sort of curiosity about what their future holds? This gives them a little glimpse, if only for a fleeting moment soon to be forgotten after the wedding is over... unless it comes true of course!
