OK, I’m an ignorant novice. So with that said, I do not understand the whole varying-and-interchangeable-lengths-of-cables-for-circular-needles thing. Doesn’t the magic loop discovery make all of that moot and completely unnecessary? The only circs I own are 60” addis in various sizes. And so far they’ve worked for any circular project I’ve done. If I’m working on a sock pattern that calls for a set-up on three dpns I follow the pattern exactly as written and just pull out three loops and presto! I’ve got a 3-dpn set-up.
When I read here or on Ravelry about people spending significant amounts of cash on needles and cables that have to be hooked up to each other and that sometimes there are problems with them such as the yarn catching on a join or a connection coming loose and other people trying to explain how to insert paper shims into the join or some other in-home repair process on a tool that’s just cost someone a fairly large number of dollars I get that fingernails on a blackboard feeling.
What is it about interchangeable lengths of cable on a circular needle that makes it worth the expense and the trouble of bad connections? How are they better than one long addi?
