Wow it s been a while. Squeeze the roll of decent crepe paper between a couple of boards and run it through a band saw.
Roll off 30' sections and reroll get some little light rubber band or drafting tape to hold the rolls.
fold a triangle in the end and wrap 10' kite string around the triangle a couple time and tie off. Reroll withthe string on and rubber band it. the rubber band is nice for holding the roll on the tail until its launch time.
There was a brand of crepe paper that worked better but I can't recall.
bag up a few in zip lock bags for storage or for handing out at a contest.
