We drew an egg template on a piece of cardboard (a empty cracker box) and cut it out. We then used these templates to trace the egg shape on the back of patterned papers (we used spare scrap booking paper). Meg had some trouble holding the template still to trace around, so we used the sticky part of a postit note to hold it in place.
We then cut out all the eggs.
After stopping for lunch we got a roll of string and used some sticky tape to stick it to the back of the eggs.
