This book is an old favourite of mine. It may not be in print now (correct me if I’m wrong, and I’d love to be wrong), but still seems to be available from many libraries and you could try finding second-hand copies through Amazon (or perhaps ebay).
Pancakes and Painted Eggs is a book for Lent and the Easter Season. It has stories, poems, songs (even sheet music, arranged by Margaret Moore), explanations of customs and festivals from a variety of cultures, recipes, craft activities, and fun illustrations by Kilmeny Niland. There’s something for everyone!
So get yourself down to your local library!

I don’t know the book, but I know and love Kilmeny Niland’s illustrations. Hunwick’s Egg by Mem Fox is another nice choice for Easter.
