Style 3724 fiberglass cloth is a 32 oz/sq yd plain weave fabric with a thread count more in the boat and tooling type range. We don't have a lot of manufactuer's info on this fabric for some reason. We will put photos of it and do more analysis ourselves. We have several thousand yards in the greige of 52 and 62" widths. Let us know if you're interested. This would be good cloth for someone to get finished and sell for heavy tooling cloth.
