Wraps make the arrows more visible for seeing arrow impact on game and they make them easier to find after a shot. You can make wraps for free by going to a vinyl sign maker and getting their scrap 3M vinyl. I have a buddy that runs a pro shop and after I told him about what I do and he said he had been buying bulk sign maker 3M vinyl for years. Use a paper cutter and cut them 6'' long by 1'' wide. I found some cool muzzy wraps with flames for $4.99 for a dozen the other day that I had to have. I will be damned though if I will give $1.00 a piece for them like most cost.
