Knitting How-To: The Long Tail Cast On
I heart the long tail cast on.
This is my favorite cast on method because it's speedy (you know casting on can take forever sometimes), it's stretchy, and it helps keep my stitches neatly tensioned.
And because I like it so much, I wanted to make sure everyone else can do it, too! Make sure you have this in your knitting repertoire and check out the tutorial video!
