It is 11:30pm at night and I realize that I need to make a hat as a teacher gift. I have the perfect yarn but I do not have the right 16" circular needles or double points. But I have a 40" circular needle in just the right size. This will do the trick for both the missing shorter circular and DPNs. How you say? Magic Loop!!!
I hunted for the best video on Youtube (also with the most views) Note: she mentions Knit Picks needles; we are carrying the Knitter's Pride Needles which are nearly identical in wood.
