No, I haven't had bad experiences. I just do not want to waste money on yarn that is not good. And I am so inexperienced, I really don't even know what to look for. I have ordered from knitpicks and been very pleased. I don't have a LYS so I can feel some of the nicer yarns before I purchase them online. I was just trying to get some ideas of what is nice.
Thank you both.
