Like most lessons in life, I learned this one the hard way. I was happily packing up my knitting for a business trip. Planning my trip project is one of my favorite parts of any travel. I was in a hurry when attaching my Chicago lace tips to my red cable. In my rush, I cross-threaded the tip. At that point, I could not unscrew the tip. I had to recruit the help of my husband. He eventually got the tip off, but now the end of the tip is bent and no longer screws down correctly on to the cable. I quickly had to change gears and plan for another project, as I only have 1 set of each tip.
However, I did learn something helpful. You can buy replacement tips and cables for this set. You can also add tips and cables to the set as needed. I ordered the replacement tips before leaving, and they arrived while I was away. Fortunately, I had plenty of other projects planned so I was able to grab another one to work on during my travels.
The moral of the story: Take care when placing and removing your tips!
