Fathers day craft ideas?

im babysitting a 3yo and 6mo this summer and i was just thinkin it would be cute for them to make something for their dad for fathers day this weekend but cant come up with any good ideas at the moment so i need your ideas! things they have to make crafts are construction paper, paints, stamps, stickers, glue, fun scissors, and colored pencils but i think i can round up some popsicle sticks, pipe cleaners, and maybe magnets.....thanks for your ideas! :)
