This may sound kinda cheap, but I use the corners off of big black trash bags. What I do is, pull the corner of the bag through fingers (using your thumb and index to make a quarter size hole) until it is about 14" long then cut it off, I then blow it up a little and tie the cut end off like a ballon. The pointed end looks like the beek and if you leave about 2" past the knot, it looks like a tail and the whole thing has a little bit of a shine. 100 trashbags run a dollar at the "dollar store". I use them with the crow frenzy tape (JS) and they seem to come in and circle right above (I don't give 'em a chance to land). Works for me. Later
