I used to love backpacking in high school, but once I started college, then got married, then had kids, I haven't done any. My 4 year old son has suddenly decided that he loves hiking and camping. After several long day hikes and camping out in the backyard, I'm trying to get some gear together to take him backpacking. We don't really have much in the way of money, so I've been trying to keep it as cheap as I can. I only have a couple of heavy sleeping bags that I'm kind of stuck with, so I'm trying to save some weight over our 8 pound giant tent from my young, stupid days of backpacking. I did order one of these from ebay:
I'm also getting a hold of some tyvek from a friend who is having a new garage built. I'm trying to put together a tent, somewhat in the vein of the Shangri-La 2, only without the pole in the back. Something with a long triangle shape in the back to cover the bug net, and a small triangle in the front to form a small vestibule for our gear.
I was just hoping for a little advice. I can't sew, and we don't have a sewing machine anyway, so I was planning to use the tyvek and tyvek tape to form something that would be a little lighter than what we have, and might get us through a year or so to make sure my son doesn't drop his interest in the whole thing.
From what I've been able to gather, I would wash the tyvek a few times with some tennis shoes, then cut out the pieces and tape them together. Then reinforce a few spots for grommets, and put those in, and that would form a mostly waterproof covering for us, in case we get caught in some rain. What am I missing, or miscalculating?
