I WISH I had the will power to make a second sock after I make the first. Or the second sleeve after the first. Or the second mitt!
This is why doing these TAAT (Two At A Time) is such a FANTASTIC shortcut! OK, it’s not REALLY a shortcut, you still have to knit BOTH, but it sure does FEEL faster! It also prevents BOREDOM of doing the same thing twice.
Below is a video of how to cast on for two at a time! You will need needles in the correct size to match your yarn in at least 40″ circulars (you’ll see why you need so much slack). It’s a bit fiddly to get started, but with a few tries you’ll be knitting two at a time before you know it!
