I received my Addi Turbo Circular Needles size 17 yesterday and OMG what a big difference. I love them so much and now after knitting 6 rows on my first afghan I can say that I love knitting straight on them. It was a little bit difficult at first since they're big needles and I use two strands of yarn but now I'm use to it. I can understand why people thought it was funny that I didn't like circular needles. I think it's all about the quality of the needles.
I was wondering if it's normal that my knitting seems to be a little loose? I imagine it's loose because of the size of the needles.
Thanks to all the people who helped me answer my questions about my afghan. I will post a picture of it once I'm done.
