Full on "blanket Cloaks" seem to be popular as well...a bit like the Rangers cloak from LOTR.....
thanks for the info looks pretty good and better still no alterations needed to the blanket, i had a picture in my head of more of a mexican/ clint eastwood type poncho, would anyone know how to make one of these, I though of simply cutting a slit half way down for my head to pop through, stitched round to stop in fraying.
