My 6 year old son has loved crafts for as long as I can remember. My advice is to get a kit together and let them create. Get them a set of kids craft scissors (the ones that cut a different edge; I got mine at Dollarama), loads of craft paper, stickers, glue, popsicle sticks, wiggly eyes, pipe cleaners etc....you will be amazed how much fun they will have thinking of things as opposed to an organized craft.
