It's important to decide if you want to stuff the eggs before you begin. If you want to keep these for future holidays, don't stuff them. Otherwise, stuff them before you decorate them. Once they are decorated, they probably won't be able to be open for stuffing. You can get creative as you want when making the eggs. Put out the eggs with paint, glitter glue, sticky gems, and ribbon. If the children want to put ribbon, and they are too young to use a glue gun, glue the ribbon on for them. Make sure the eggs are completely dry before continuing with the project.
Baskets
Make a flower for the edge of the basket with crepe paper. Using about 6 inches of crepe paper, fold the paper into folds, then tie it in the center with florist wire, leaving a long tail of wire. Then spread out the petals of the paper, and you should have something that looks a little like a carnation. Play with a few to get it right. Make enough flowers for however many centerpieces you want to make. Set those flowers with wire tails aside. Take a bowl and using the wire on the flower, attach the flower to the bowl. You will want to bend the wire so the flower sticks out and up. Do this for each bowl you have. Take the hot glue gun and glue the edge of each bowl, then put crepe paper all around the edges of the bowls, about six inches should do it. Leave that to set a few minutes before you go on. Put some Easter "grass" in each bowl, and then some of the decorated eggs. Leave room for the bird. Set aside
Birds
This is so simple! Get a pom pom, about 1 inch round, and using the hot glue gun, glue one large feather on each side for the wings. Glue a smaller pom on the top for the head. Cut a small triangle out of craft foam, and carefully glue that to the head, making sure the pointed side is facing out. Make a bird for each completed basket.
Finishing Up
Put a bird in each basket, trying to coordinate the colors are much as possible. Put the centerpieces away in a safe place before use
Notes
Be creative as you want with the eggs. Have a look at some real Fabergé eggs for inspiration.
