My students made Easter bonnets ... well, the girls did. The boys made bunny ears.
We took gift wrap (the floral kind works best) and cut a big square out of it. Big enough to cover their head. Then, I covered the girls hair w/a shower cap and tied the gift wrap to their head. Then, I took spray starch and sprayed it all over the gift wrap. I curled the remaining paper up into a brim. When it dried (on their head), I sprayed it w/more spray starch. Once that dried, we tied on a tulle bow and I hot glued silk flowers to it. Very, very cute. The girls loooved their bonnets and their moms thought they were just darling! We had a parade around the school.
As for who wears Easter bonnets to church services, it's the little girls. It's rare if I see a woman wearing an Easter bonnet or even a hat!!!
