Best Answer:I haven't had experience with the kite material, just the ribbon material. They worked really well. My students LOVE the ribbon streamers. The only issue I noticed is when they would whip the streamer too fast, students would find their ribbon tails in a tie/knot. The knots came out very easily, but that was the only problem. Besides that, they're awesome! :)
I got the ribbon material, and they look beautiful. They do tangle when some of my littler students use them (probably because they don't control them as well when doing swirls etc.). Mine have not frayed and still look brand new. I've made my own with more plastic-like material and did not like the way they looked as they flew through the air very well.
A ribbon material would be nicer than this kite material in my opinion. These are fine for my purposes but I thought they would flow more when my students used them and they don't flow through the air very nicely.
