Maybe it’s just the name, but I see ladybugs as being more a girl ‘thing’ than for boys- but you parents of boys can decide that. But I sure can see the little girls loving these hats as their take home party favor!
These look a bit complex for preschoolers to make as a party craft, perhaps not if they’re a bit older in elementary school, but you can spend a bit of time (not too much!) making these ahead of time to send home with them as their favor. While you wait for the parent pick-up, have them all outside pretending to be ladybugs.
