I use this same idea. I have a roll of freezer paper on a wire and I pull down a 3ft piece and use a stencil cut out of bulls eye to paint on the section. Pull down another section, paint and shoot again. Super cheap set up.I bought a 1000 foot roll of butchers paper online, about 36.00 delivered. I then made full and half size IDPA silhouette patterns out of cardboard and traced them onto the butchers paper. The patterns also have the -0 zone cut out and I use a Sharpie to draw the circle. They are then cut out. I can make about 400 full size silhouettes out of one roll. The butchers paper is tougher than standard target paper and works great.
