Eggshells can be used to create a faux mother of pearl decoupage trinket box. First, choose a box. The size of the box will determine the amount of eggshells necessary to cover it. Remove hinges to remove the box top and place to the side. Place eggshells in a strong plastic bag and use a rolling pin to crush them into fine pieces. Spread decoupage or white glue over the top of the box. Sprinkle a generous amount of eggshells onto the glue and gently spread over the entire surface of the box top. Press the eggshells firmly into the glue. Shake off any excess shells. Repeat the process on the sides of the bottom of the box. After this layer of shells is dry, repeat the process for a second layer. Then let the box dry overnight. Brush or sponge white or ivory craft paint with a pearl, iridescent or shimmer finish in a thick layer over the shells. After this paint is dry, apply a second layer. When second layer is dry, reattach the top to the bottom of the box.
Die cooked eggs with Easter egg die using one or multiple colors. Peel the eggs and crack the colored shells in small pieces. Coat one side of a Woodsie with white glue. Woodsie's are 1/16-inch thick pieces of wood that come in a variety of shapes that can be purchased online or at arts and crafts stores. Stick eggshell pieces onto the Woodsie colored-side up to completely cover it. Allow glue to dry. Break off any sharp edges off the exterior. Use a hot glue gun to attach a jewelry pin to the back of the Woodsie.
Draw a picture or use a coloring book page as your design. Cook and die eggs in various colors needed to bring the picture to life. Peel the eggs and place the shells in separate zip-lock bags by sorted by color. Crush the shells into pieces. Use white glue to attach the shells to the picture and allow it to dry.
Cut the top off an egg with a kitchen knife for a rugged cut or a razor blade for a cleaner cut. Use hot water to clean the membrane from inside the egg. You can draw a design with markers or color the outside of the shell, or leave it natural. Brown eggs can give a more rustic look to your planter. Fill the egg almost to the top with potting soil. Then sprinkle a teaspoon of grass, rye or wheat seed onto the soil. A tiny plant sprout can also be planted. Sprinkle a thin layer of soil over the top of the seeds. Carefully water the soil, being sure not to overflow or soak it. Place the egg planter in an egg holder and place in a sunny spot. The seeds should begin to sprout in a day or two.
