Well, it's not going to help you guys much, but my wife sews mine using heavy unbleached muslim. We have been together for 21 years, and I am still using two of the first four, and two more ten or 11 year-old replacements. Coues whitetails fit in one bag, big mule deer take a couple, and all four will hold elk quarters and left-overs easily.
Muslim, or muslin?
