Erica, that's a great question and, if I'm honest, I'm not sure how it works with a long-tail cast on. Probably the best way to tell is to try casting on with a highly variegated yarn and checking the length of one of the colour repeats before using it in the cast on and then measuring it again once it's on the needle.

Or as an alternative, you can download our free ebook and try designer Sarah Wilson's tip for never running out of yarn during the long-tail cast on, a special technique she calls the Texas Long-Tail Cast On. Click here to get your copy!
