2-Color Long Tail Cast On for Double Knitting
Create a smooth, low profile edge for your double knitting with the 2-color, long tail cast on! Using a 2nd color in place of the long tail, you can alternate between picking up stitches in the two different colors.

Normal Long Tail Cast On
Before trying this cast on, it helps to know the long tail cast on first. If you’re not familiar with it, here’s a great tutorial from Marly Bird. Here’s another one from Jessie at Home that shows how to start without a slip knot!
Set Up for 2-Color Long Tail Cast On
Slip knot
The 2-color long tail cast on starts a little differently. Instead of using a long tail, we’re going to use a 2nd color. First, hold both yarns together and make a slip knot with both colors. Place this slip knot on the needle.

The slip knot is just to secure the yarn and does not count as a stitch
Grip
Hold the needle in your dominant hand. Now grip both yarns in the palm of your other hand. Then, place your thumb and index finger between the two strands of yarn, separating them.

Turn your hand so your thumb and index finger are pointing up. You should know have a V or slingshot shape. This is your starting point.
There is a loop of yarn around your thumb, and one around your finger. Each loop has an outside strand and an inside strand.

If you care which color you start with, make sure that color is on your index finger. In most cases it won’t matter, as double knitting is reversible.
2-Color Long Tail Cast On
First stitch – finger color
The first stitch is done just like a normal long tail cast on. Bring your needle up from under the outside strand on your thumb.

Then bring it down over the inside strand on your finger and scoop up the yarn from your finger.

Pull the yarn from your finger through the loop on your thumb, drop the loop off your thumb, and tighten. Then re-adjust your grip back to the starting point.

2nd stitch – thumb color
For the second stitch, we are going to go in the opposite direction. Bring your needle up from under the outside strand on your finger.

Now bring it up from under the inside strand on your thumb. Be sure you’re going up from the bottom this time instead of down from the top. If you go the other way you will end up with a twisted stitch.

Pull the yarn from your thumb through the loop on your finger, drop the loop from your finger and tighten. Then re-adjust your grip back to the starting position.

Continue casting on
Repeat this pair of stitches until you have enough stitches cast on. Remember not to count your slip knot. The stitches on your needle should now be alternating in color.

If any stitches did end up twisted, just work them through the back loop on the first row. When you reach the end of the first row, remove and undo the slip knot.
