I use a bundle of yarn. Cut a series of 24 inch pieces, 20 or so. Fold that bundle in half and then wrap a another piece around the fold to form a donut to tie on your pack or quiver. Call them pony tails. When on a blood trail, simply pull a strand out and wrap on a branch. Discreet way of marking a blood trail. Easy seen to determine a line of travel.During tournament season, I use them as self-cleaning device to wipe dust and dirt off missed shots! Yep, miss a lot.... If I were back east, I would tie on e on a branch with scent to attract and mark ranges.
