I am not a Magic Loop kind of a girl. Sorry, I'm just not cut out for it.
I'm trying the Magic Loop for the first time and it's taken (for ****) ever to knit this pair of socks. I'm using #0 and a k1p1 ribbing (top down). I started with 24" circs, having confused the directions for using 1 or 2 circular needles. Then, thank goodness, I learned that for 1 circ. a min. 40" circ. is recommended while for 2 circs at least 20" circs are recommended. ( Actually, for 2 circs, there is a range of recommended needle lengths and combinations.)
Magic Loop appealed to me because I tend to shed needles on the bus and because socks are my favorite commuting projects.
So, there I was, on the bus all summer and fall, straining my hands to get the 24" circ around. In the LYS in Southern Shores, NC, the yarn store salesperson and official sock afficionada revealed the secret of 40" circs for Magic Loop. With great anticipation I changed needles, hoping it would speed up the knitting to my usual pace. It has but only a little
But, the #0 and #1 Addi Turbos (here imagine Brenda's Addi whoooosh sound) do not pull smoothly through the stitches. Those are the 2 needle sizes I've tried. It takes a little finagling to getting the stitches to glide over the needle-to-cable join. Annoyingly enough, I calculate that I don't save any more time than I would switching among four needles.
Conclusion: for me (no universal claims here!!) the Magic Loop is perfect for a project with a low completion priority and where dropping/losing dp's is an issue.
