Could do this with the Cricut. vinyl, and a cheap plastic bucket. Good idea for the kids.
Apply stencil to the egg, rubbing the inside edge for a good seal. Using a cotton swab, dab undiluted food coloring inside stencil; let dry before removing stencil. To create a dark egg, make red and blue dots first, and then smooth circle stickers onto the shell. After a dip in inky-black dye, the stickers are removed.
