I haven't been checking the site as often as I used to and this area even less so luckily I noticed it before more than a week or so went by.
I like the sewing kit idea a lot. If you are super outdoorsy you can make a fishing line out of it. I sometimes carry a shovel, in winter, I just didn't think I used it often enough otherwise.
What kind of sleeping bag are you going with? And have you weighed your pack?
I don't always carry a sleeping bag but always have a military poncho, poncho liner (which is like a lightweight but fairly warm blanket and easy to pack) and two emergency blankets
