Sir Charles, I understood your intent well, I think. If four thicknesses were necessary thats the way I would try to handle it, using glue to tie the first outer folds down. You could then just finish it in a manner similar to a money belt, with the final stitch line serving as the upper edge. I have never made a belt from the webbing but have made a couple of pairs of suspenders from 20oz tarp weight canvas by using the method described in my first post. If the weight of the advertised 32oz stuff relates to 20oz painters canvas in the way I would think it does, that is already some pretty heavy/stiff material. To do this in a way that looks like one heavy thickness, could one one start with a 12"W strip, fold it in half length wise and then sew down the center lengthwise. The results will now be a six inch wide strap of double thickness with a stitch line running the center length, three inches from each edge. Take these results and fold/press the remaining 3" wings back on each side of the soon to be belt. At this point I would tac/sew the outer doubled edges, well, to create a tube. (I think glue would create too much stiffness) With three inches to work with and some muscle you should be able to turn the layers inside out. You could now lay it out in such a way as to allow the one central seam to fall at the back c/l of the belt where it would be concealed to possibly give a more single layer appearance. With a bit of extra layout, the cartridge loops could be sewn as to not show on the backside and do not forget to add for fold and sewing allownaces. Sir Charles, this is the way to do a confusing post. Boy am I glad that I do not like to wear canvas belts!!!!
