First of all, here are a few things to avoid: plastic grass, plastic eggs, plastic basket, plastic toys, and plastic-looking candy.
Instead of buying a new basket, use one you've already got on hand or... Make one! Martha Stewart has an adorable berry basket makeover as well as a paper bag basket how-to. Or, ditch the basket idea and fill a clean terra cotta pot with goodies for an extra springy touch.
Eco-friendly basket fillers don't have to be any less cheerful or colorful than their earth-unfriendly counterparts. For starters, make some homemade cascarones (confetti eggs) to replace the plastic kind.
As for the sweets, either shop for fair-trade chocolates and organic candies, or opt for making your own sugar cookies, candies, and even peanut butter cups (a family favorite in our household for Easter).
For an added green bonus, give seedlings for a starter garden, handy and bright reusable bags (or a set of reusable snack bags for a young kid), or a hand-printed organic cotton T-shirt in lieu of toys.
