    Do you use a special needle and type of thread?
    Also how are the seams made to be waterproof?

    I don’t use any particular needle. You want to use nylon or polyester thread, not cotton, for durability reasons. I just use regular thickness Gutermann polyester thread, my theory being that in using lightweight fabrics, I want the thread to fail first, because that can be field-repaired. If the fabric goes, that’s a lot harder to fix, especially in the backcountry. A great source of information for making your own G4 is the Yahoo group: G4-Pack. There are many knowledgeable members who are very generous with their experience, some of whom have made multiple packs.

    My first gear making project was a camping hammock and a basic 10 x 12 tarp. I eventually made a backpack-like object. It never really worked that well, but the hammock and tarp serve me well to this day.

    Sewing, like gardening and woodworking, is one of those lost skills, but I’m happy that guys like Glen and all the early ultralighters have really rejuvenated this skill.

    I’d like to make something like this and attach it to a lightweight external frame. I think it would be the best of both worlds; lightweight and cool. Plus the added plus of having a frame to attach odds and ends to if it became necessary to do so.
