Easter bonnets for boys

[SarahHillWheeler]

I love the idea for easter bonnets for boys on mumsnets. www.mumsnet.com/easter/easter-bonnet-ideas-for-boys
For past years, I have (badly) adapted base-ball caps and various hats with ribbons and little toys - the results of which have been largely hideous (for my pathetic attempts, see crewcutandnewt.com/2012/03/15/easter-bonnets-for-boys/)
I'd be interested to see what other mums have done, or are planning to do. Sadly, at my son's school, it can get quite competitive - which kind of distracts from the fun of getting the little ones involved themselves.

We made DS1 a large top hat shaped hat out of yellow card. It was amazing .

Sounds great, makes me think of a sort of Easter Willy Wonka (or maybe it's just a Johnny Depp thing).

This year, I may customise a cowboy hat. Fabric paints (green) and then sew on some felt eggs and insects and things - lasy year I definitely overdid the flowers!

We have the challenge of Easter bonnet from recycled materials.... Bang goes my idea of buying up craft shop!
Luckily have old straw hats and egg boxes but what else? Any ideas?
