Campfire blankets are great to wear in the evening as an extra layer, & an excellent place to put your old badges on (such as beaver badges earnt that can't be transferred to your cub uniform).
The page also has a link for those who can't or don't sew ...ready made reinforced taped neck poncho blankets from the scout shop website, (though sadly there is no mention of the material quality or variety used).
Hope the new page is helpful!
