Getting ready for winter

 With winter coming, it's getting a little colder, and we're all keen to wrap up warm.  But among all the snug jumpers and mittens, let's not forget about our chlorophyll-bearing friends.
 (This comes from a suggestion from Facebook.  The hats are for the Innocent Smoothies campaign, and have been sitting in a box waiting to be sewn up for an embarrassingly long time.  No plants were harmed during the making of this.)

Enjoy,
Hugh.
