Making my first underquilts. I ordered two kits from ripstopbytheyard for 3/4 length underquilts. Was planning to make them this weekend for a trip next week. Just realized I only received one piece of the Climashield Apex rather than two and I don't know if I can get another piece in time. The piece I received is 74x60. Plans for the underquilt say to make it 53x46. My question is, if I made the quilts 37" wide instead of the standard 46" wide, would it be adequate? Won't be using for extremely cold temps, but possibly in mid 40's. It would be total of 9" narrower or 4.5" on each side. Maybe it would still be fine?
