I have talked my girlfriend into making a big down blanket out of 20oz of 750fill down. She has done a little sewing here and there but I want to keep it as simple as possible. I think we are just going to make a big rectangle.
The idea is to have this be multi functional. I was thinking we could make it out of momentum 90 and then make a soft fleecy zippered cover for it that we can take on and off. This way we can use it around the house as well as a comforter on a twin bed for our future kid. Then when we want to go backpacking we can take the cover off and use it out in the woods. It will obviously be a little heavier than it probably needs to be but even if it was 40oz or so it would still be a little ligher than what we are carrying combined now (golite ultra 20 for me and synthetic cat's meow for her. And I think it would be warmer.
I have checked out thru-hiker a little and read the quilt instructions on that site.
My questions are: what do you think of this idea?
What size would you recommend? I'm thinking 75in long and 60in wide. (I am 6' 165lb and she is 5'2'' 110lb). Since it will just be a rectangle I would like for it to be long and wide enough to tuck the feet under and obviously the sides.
I feel like sewn through baffles would be much easier for her, how much warmth do you lose? %?
Thanks for the help!
