Use golf tees to stake balloons to the ground. Could line the sidewalk and/or driveway for a welcoming home greeting, make a path to show the way to a backyard BBQ, receiving line at an outdoor wedding reception.
Flip-Flop Cake--trace bottom of a child-size flip-flop onto cardboard then use stencil to cut shape out of a pound cake and layer it with ice cream. Oh how fun, how fun! I adore flip-flops anyway so this is just extra special. Betty Crocker must have read my mind!
