So, I’m finally ready to start using circular needles! I know they come in different lengths depending on the circumference of the project. My question is: How is the length measured? For instance, I’m looking for size 17 24" circulars. Is the cable supposed measure 24" or is it from one tip of the needle to the other tip? The reason I ask is that I’ve compared the same needles but have gotten different lengths…hence my aprehension to use circulars!! Any help would be greatly appreciated!!
