I did stuff like this.
This is a duck egg. It has a trimmed window cut in the back. I made all sorts of things from duck eggs and goose eggs. Jewelry boxes, nicknacks, nightlights.
The base is a wooden egg painted gold. The lattice is white bugle beads and silver seed beads. The flowers, leaves and vine are seed beads.
I make beaded flowers using wire and seed beads.
I am getting my first chicks in a few weeks (March 6-8). I can't wait.
