I love these moss covered eggs.  I found them on pinterest and I wish I could give someone credit, but there was none.  Regardless, these would make a great spring or Easter display.  Start with styrofoam egg shapes, hot melt glue pieces of moss (easily purchased in any craft store) onto the eggs and press lightly being careful with the hot glue.  When covered, wrap in twine and glue on small flowers.  These could also be wrapped with ribbon or raffia to match your presentation and décor.
