Oh my goodness...you gals are all so awesome!! So many good pointers here!! I talked to my customer and she was using another regular pony o first, then the streamer one and it's coming apart and it was the first time she had used it...not good!
I have the Goody ones right now. They aren't the super thick ones, and the black were all gone, so I have the multi colored pack. I'll have to look at the Dollar Tree and see what they have. I remember looking quickly before, and I guess I didn't realize I should be looking for very thick ones.
