A craft revisited. I first used this idea here. Colored egg shells are used this time to enhance a frame.

Dye your eggs with a mixture of food coloring and vinegar. Peel the eggs and remove the membrane. Separate the colors. An empty egg carton is good for this.
Paint an area with glue, about 1" square on the frame. Place a piece of shell on the glue and press down with a wooden skewer. The shell will crack. Reposition pieces of the shell with the skewer if you need to. Repeat until the frame is covered.
Fill in any large gaps with scraps of shell.
