Its in Swedish so you will have to allow google to translate for you but Ikea has some beautifully earthy ideas for easter on their blog.   This arrangement with the textures of grass, quail eggs, feathers and dirt mixed with the fresh greenery of spring bulbs perfectly captures the season.

Have you ever died eggs with natural ingredients like beets, or onion skins?  These naturally dies eggs but they take it just a bit further by placing leaves over the eggs during the dying to create natural designs.

Full instructions (use a translate tool) can be found at the ikea site.
