Well, I have been working on a quilt for a few days now and am now semi-finished. I have yet to finish the seams, add drawcords, velcro, etc.
Overall, I'm pleased with the project. If I had it to do over again, I would probably use 1.1 oz for the shell and possibly the liner as well. I used momentum.90 from thru-hiker this time and while it is nice, it probably isn't worth the extra money (maybe for the liner) and it doesn't save much weight.
I haven't measured for the final dimensions but I did weigh it. Right now, it weighs somewhere between 20 and 22 oz. It is stuffed with 12 oz. of down and lofts to over 3'' in most places.
