Hi all, does anyone know where I can source the above? Ideally something about 3-4mm thick that I can stitch with my sewing machine (an industrial leather machine). I'm aware of Sundeala, but that seems to be too thick, this needs to be thinner, I need to stitch some leather to it. Can anyone offer any alternatives? It needs to be fairly rigid, and ideally have some water resistance, (although I can treat it). I need about 2' sq, but it doesn't have to be square as I'll be cutting it to fit.
