We've just finished ours at lunchtime!
Fortunately, I had an old straw hat (small) in the cupboard - left over from DD1s fancy dress outfit.
So DD2 and I used tissue paper round the sides, then on top I made a little basket, which DD2 coloured in. We've stuck this on top of hat and screwed up some green tissue paper inside, then placed some little chicks (bought from Birthdays shop) inside.
Around the rim, more tissue paper with more chicks and some egg shapes that DD2 coloured in.
Easter Bonnet parade is tomorrow at nursery - and I have no excuse not to do it - as I work there!!
