If you are familiar with the long-tail cast-on method you’ll find this two-color cast-on method easy to use. This is an ideal cast-on method for double knitting projects but you can also use it also if you simply want to make the edge of your project a little bit prettier.
Step 1: Setup
First, make a slipknot with color one (turquoise) just as if you would make it when you are about to do a long-tail cast-on with one color.
Then with color two (orange) make a slipknot right after the first one.
Step 2: Pull both strands of color one between the strands of color two
Step 3: Make a stitch with color one as if you would do when using long-tail cast on with one color.
Step 4: Repeat steps 2 & 3 with color two
Pull both strands of color two between the strands of color one and make a stitch with color two.
