My regular needles are a set of 10+ year old Symfonie Interchangeables so I was interested to see what's changed as well as reflect on why I still love these needles. Interchangeable needle sets give the knitter lots of options, they're not just for knitting big garments in the round but also great for big flat items like blankets, smaller round items like hats, smaller circumference rounds items using magic loop and even for small flat objects like leaves.
