I was web browsing various flies recently and found a few tied with the foam bodies,looked good ,so i found a vendor selling them,not cheap either! then it occurred to me exactly how they could be made,a 3mm hole punch used on a kip mat like the type used for camping,simply punch a hole through the foam and the 'waste' is the bit you want,as i sit here i am considering using some of the kids floatation tubes the use in the swimming pool as they come on a plethora of colours.
so here is a quick try out,seems to look ok and of course is incredibly buoyant,what are your thoughts?
