Trick and treat?
There's something amazing about pumpkins: great soup and pies and rather inspiring to craft workers ...
Whether traditional or some of the more amazing carvings, some of which are quite gross ... but anyway, the other thing is that they remind me of the shape of the traditional tea cosy! There are plenty of pumpkin tea cosy patterns out there, but the traditional ridged design keeps the tea much hotter than just a rib version.
So I looked around for some free designs and found two excellent examples, at http://www.instructables.com/id/How-to-knit-a-quotproperquot-English-tea-cosy/ and also http://teabythesea.blogspot.co.uk/2008/04/grannies-traditional-tea-cozy.html
