Tweed cycling fashion victims

A big wall in China - how great is that?
A small outdoor social event in a village - how fete is that?
A handy table for DIY - how Black & Decker Workmate is that?
Two galleries in London - how Tate is that?
Someone who doesn't appreciate what he's been given - how ingrate is that?

A mixture of black + white - how gray is that?
The opposite of night - how day is that?
A fireman - how brave is that?
After April but before June - how May is that?

am I getting this right .. ?
