I'm expecting to sew a two-person quilt and a 5x9 sil tarp this weekend. The quilt, made with Momentum and 5 oz/yd^3 Climashield XP, should weigh in at about 24 oz. The tarp (5x1.35), including guylines (1), 8 stakes (0.35/stake), line tensioners (8x.05) and 3x6 sheet (~4.3 of Tyvek should weigh in at 15.25 oz, not counting thread. Not too shabby, me thinks.
More details and possibly photos when the weekend is done.
