For Cinco de Mayo in Kdg. - Plastic egg maracas - plastic easter eggs, fill them with what you want (candy, beans, etc.) 2 plastic spoons, wrap in colorful duct tape or plain masking tape and hand decorate.
cityscape - I love the black line drawing against the richly colored skies. * I think I would add colorful water below to balance it and show the "colorfulness" of nature contrasted by the black and white of the city.
