Hello. I'm making a bushcraft type backpack that will have a mix of leather and canvas parts. I made prototype that turned out really well except for the parts that I used barge to attach the leather to the canvas. For example the leather bottom to the canvas bottom and the leather buckle attachment to the canvas front. You can tell the cement "bled" through. My canvas is light/medium weight - sort of like a carhart jacket exterior fabric.I suppose I could just rely on the handstitching of leather to canvas but since this is a pack, I want it as strong as possible. Another option is a different adhesive but won't those others bleed too? (I only have Barge and plain Elmers but I'd be willing to buy something else if there's a suggestion). If it's a water based adhesive, how is it affected if the pack gets wet? I do plan to waterproof the canvas with a hot beeswax, parrafin, and boiled linseed oil mix that I saw online. I'd love any input.
