Myrna's question: "I want to know how to change needles in the middle of a project. For instance, I started with a circular needle that is too short and I need to change to a longer one."
So, Myrna and everyone else, this is what to do (PS - it's very easy)...
You can do this if you've got a project on DPNs that you want to switch to Magic Loop, or in my case in the video, I wanted to switch from Addi Lace needles to Addi Turbos so I could speed through the cuffs of my socks. Enjoy!
