They are very warm and one size fits all as they are stretchy. Chris is a huge fan of them (not the feminine colours I might add) and has a few in his wardrobe. And I too have a few that I shove on when its cold out. And at £14 they are not badly priced.
Her fingerless mittens are fab, warm and snugly but lots of room for movement. Great for Mum's on the go, shopping, outdoor selling (for you crafters out there) and I have to confess I have even worn them in my studio when its been chilly.....totally practical for sewing :D Mittens are £8
She has a wide variety of colours and if you would like something in a particular colour she is more than happy to knit them for you.

My favourite beanie in her shop has to be this one, so pretty with all those flecks of colour.
