I agree with a lot of the others. I use yarn I feel is appropriate for the object. I like RH or Carons SS for afghans as they are going to take abuse and be washed regularly. I like the KP Palette yarn I bought for socks and just bought some washable merino from LYS that was waaaay more expensive and don't find it any better than KP. I also spent 7.50 a skein for bulky yarn to felt for slippers, I probably would have been better off at Michaels and buying what they carry at 1/3 the cost. I am knitting frantically to finish my merino socks so I can cast on the bamboo for my next pair.
I prefer getting yarn on sale, but am weak when in the presence of pricey yarns.
