Lumi Sheet 2" x 3" patch - cotton backed. It is not for us to dictate its use, but to advise on experience and ideally suited to create hot spots and trigger points on lure and fly patterns. Easily cut into strips of various widths, it is a simple matter to tie into thorax, shell backs and use and overlap to create segmented abdomens, do not overstretch and a little warmth ie warm water does make it more pliable.
