These crackers can be made by young children as well as adults. I have made them with children as young as Year 5, no problem providing that each component is already measured and cut out for them.
Adults: you may make these for the dinner table as you can choose a nice gift for the inside instead of silly items, you can make each gift suit the person and label the cracker up as a dinner seating arrangement. The cracker snaps can easily be ordered on line and by replacing them each year, these crackers become re-cycleable.
Have fun...
