Lucky Dip Ideas

Hi! I have a stall at a summer fete coming up and someone once told me that the best way to get people interested in your stall or to get children (and their parents) to stop and look is by having a ‘lucky dip’. I was thinking of sweets attached to a crafty something (to show what I do and encourage the parents to buy something from me!) … I was thinking of an inexpensive and easy to make key ring, but thought it would be boring for the kids! Any ideas for something easy and cheap to sew that kids would love??? Thanks!
