I am trying to make a ripply scarf and in a pinch because my circulars could no longer hold the number of stitches I had, I needed a pair of MUCH longer circular needles. Turns out Addi Turbos are the longest I could find. I had never had the chance to work on these knitting needles before, but I have to say OH MY GOSH!!! they are so wonderful. I had no idea what I was missing! The stitches just glide right off the needle...They probably would be tough needles to learn on, but are oh-so-wonderful once you know what you are doing.
