If using a Cricut, score center of the egg vertically with the scoring wheel or tool. If using a paper punch, fold the eggs in half lengthwise and crease with a scoring board or paper creaser.
Glue egg shapes together with the folds fanning outward one at a time with a glue pen. You'll attach the left side of one the the right side of the next one and continue.
Before gluing completely together, add a ribbon to the center to use as a hanger.
Notes
This technique can be used to create Christmas ornament too! Just use festive Christmas cardstock or whatever colors you want.
