I love KiwiCrate.com, a service that provides mail-order crafts and projects for kids.  This awesome service sends you one crate a month, which includes a couple of crafts or projects with a particular theme.  Available themes include dinosaurs, colors and gardening.  I think it would be especially great for busy moms and dads who don’t necessarily have the time to plan out projects or shop for supplies.  Such a fun idea and an awesome gift idea!
