My kids love to glue things so I taped a big egg on the wall and gave them tissue paper and easter themed stickers to decorate it. It was fun for a while and Kaley kept coming back to it to stick a few more peices every now and then.
This activity is so versatile too and could be slightly changed for pretty much any theme.
I wish I could remember what they are looking at so excited like but...
Here they are decorating it:
