On Saturday I was sitting knitting my Lotus Blossom Tank when the plastic piece of my 40" cord came out of the metal screw-in part. I tried super glueing it in, but it was unsuccessful, so I put in a call to Knit Picks, and even though the set was ordered almost a year ago, they are replacing it free of charge!
Then today I'm sitting knitting a pair of felted clogs and the same thing happens to my 24" cord! So I feel silly, but I put in another call and they also happily replace that cord. I'm glad their customer service is so great, but I really wish these cords would stay together, I've got tons of Christmas presents to knit and no time to wait for new cords!!
