I'm working on a sweater right now and I reached the dreaded (at least to me) point where I needed to move my work onto a longer cable. I have interchangeable needles, so in the past I've always threaded the longer or shorter cable through the live stitches then moved the needles around.
I've got the summer plague and as I was drifting off before my third nap of the day yesterday I had a minor epiphany.
*If I just took the right needle off, replacing it with an end cap, then put that needle on the longer cable (with an end cap on the other end) I could avoid the mind-numbing threading and just knit my way on to the longer cable.
Exhibit A:

(needles and knitting ready for the transplant)
Exhibit B:

(new cable on the top, old cable on the bottom)
I'm feeling rather clever for discovering it myself, which means that it's probably common knowledge amongst knitters with interchangeable needles. Buuuut, I thought I'd share just in case it's news to anyone else.
(10 pts. to your House if you can recognize the mess I'm knitting)
