What can I do with my two granddaughters (aged 4 and 5) on this rainy Easter week-end?

There is a cute craft idea to make Easter crosses here: a href="http://www.celebrationideasonline.com" rel="nofollow"http://www.celebrationideasonline.com/a in the easter celebration ideas article..all natural items make the cross, so you could gather things from around the yard. Also plan an easter scavenger hunt.. there is an idea in that article too.. you could adapt it to place the hunt items in the house if it is raining.
