my girlfriend and i are going backpacking and wwoofing next summer and i'm sick of carrying heavy kit so intend to go ulta light and enjoy the travelling more. we find two sleeping bags zipped together waaay too big for the two of us and it gets cold. therefor we want something smaller that two bags and i figured we either look for a twin bag to buy (not likely), make an extnetion piece for an existing single bag or make a new twin bag.

does anyone have any experience of twin sleeping bags? or making bags?
