In my search for a more professionally finished sack (not wanting the weight of a simple grommet) i started making sacks like described in the Ray-Way kits, with an extension of fabric past the drawcord. This allows me to make a separate drawcord tube and sew it in for a nice finished looked with the added benefit of a waterproof closure (doesn't help if i don't seam seal the sack). The added weight of the extra fabric is less than a grommet and i find it helps me get items in that are a tight fit as they are in the collar then get pushed down. For the rest i make a square bottom sack as it is easy and holds up great. Its my way, it's not the best way, but it works for me, and I guess for Ray too. I actually did it without thinking of Ray's but realized it was the same just now as i was describing it.
