I make mine out of camo mosquito netting, not waterproof but they work very well, take a piece of skeeter net about 6" wide and about 32" long fold over the last two inches to make a J then simply hand sew those two 2" edges, this covers the fletch as well as the arrows shafts, use velcro tape on the top of the net and the other half strip on the hood of your quiver, just place the J part over your nocks and velcro to the top of your quiver--------done
this is very effective way to hide fletch as well as shiny shafts, I leave one arrow exposed, if you need a second shot just pop the skeeter net off the next nock,
netting is very light wont absorb water and very cheap, if i get in thick brush i take it off so it doesnt get hung up, I carry a couple with me in case I lose one.
here in CO reflection or shine is far more important then camo color, I see quiver loaded with new arrows they look like a signal mirror, same goes for bow limbs.
