I am rediscovering these now that summer is gradually fading and before switching during the colder days to Brooks cashmere and Press lambswool.  I used to have quite a collection of - mostly - Tootal with some Duggie and Sammy.  They seem to be getting slightly more difficult to track down in shops, though.  I was offered a 1940s rayon example back in June.  Some are double-sided.  I think they add a slightly jaunty touch.  Fading yellow looks nice with grey London Fog, dark green with brown Burberrys'.  I think The Beatnik is a fan.  Paisley and polka dots are both nice and remind me of Clothesville.
