I will test it out as is, and if necessary I will try to get rid of the gaps. I have some scraps that i will weigh. I tried it out the other day when the wind was blowing about 20 mph (on a farm in an open field on top of a hill) and the temp was about 40 deg. F. Felt fine. Will try it near freezing temps and let everyone know. This vellux stuff seems real promising. My aunt has a couple of them, and she swears by it as a good blanket to keep warm around the house.
Of, forgot to add the dimensions. It is 4.5 feet wide by 6.5 feet long. Just enough to go from head to toe, and wrap up around me in my hammock.
