RE: source for streamers?
Party supply stores have crepe 500' rolls <2" wide. Put rolls in freezer for a couple hours and then cut in half on band saw. I put two chairs 30' a part and make eight trips around to roll off a 1/2 roll of crepe. Cut both ends and 16 streamers ready to roll. In a variable speed hand drill, I chuck up a piece of 3/8" dowel rod which has a cut to allow the streamer to be held to start the wind. Trial and error has solved a few glitches. Make a couple 8" diameter pieces of coroplast with a piece of 1/4" dowel rod which is used to put the 1/2 roll of crepe prior to unwinding. Otherwise a big mess. Mount the drill on a table and plug into a light bar where you can hit the on/off switch prior to and immediately after the roll up is finished. Put a couple rubber bands around the drill trigger and adjust drill speed so as to have a manageable speed for rolling streamer. Buy bag of #10 rubber bands (small) to secure the streamers after the roll up. Hope this is not too confusing. You probably better off and buy from Hattrick.
