I made this wreath for 3 bucks. Seriously. Okay, I already had blue and yellow spray paint... but you could make this for under 10!
I bought the eggs, the green styrophome wreath base, and the moss all at the dollar store for one dollar each. (I went to Dollar Tree). I spray painted the plastic eggs, and flecked them with brown paint and a toothbrush.
While they were drying, I just used some hemp string to tie around the green base (to hang it), then a hot glue gun to attach the moss. After the eggs were dry, I glued them on as well. The whole project only took about an hour. Cute, cheap, easy, and well.. you can't see the egg seams if you stand back. ;)
