Tutorial: Double Knitting – Cast On

Tutorial: Double Knitting - Cast On

To start double knitting we need to cast on. Since we create two layaers of fabric we have to cast on twice the amount of stitches of the pattern. At the beginning it looks like there were too many stitches but after some rows/rounds it all falls into place. Each stitch of a pattern comes in a pair. This usually means one pair consists of 2 colors. I tried 3 different methods and want to share them here. I put them all in one swatch to make it easier to see the differences.

Make a slip knot. The slip knot is not the first pai of stitches, it will slip from the needles after it’s purpose is fulfilled.



For every cast on method shown hold your fingers and yarn like this:

Method A


for the blue stitches: put the needle in the thumb loop from under the loop


Pull the blue yarn through the white loop


let the white loop slip from your thumb and pull it slightly to form the first blue stitch


for the white stitch: push the needle in the index finger loop from behind


wrap the white yarn around


let the blue yarn slip from your index finger to form the first white stitch.

Continue until you have the amount of stitch pairs you like.

Method B

For the dark yarn use the same cast on as in method A (first 3 steps). For the lighter yarn use the following steps:


for the white stitches: go through the blue loop


push the needle in the white loop


pull the white loop under the blue yarn and let it slip from your thumb

Method C


with your needle go under the white yarn


then put the needle over the blue yarn


pull the blue yarn up from under the white yarn




for the white loop put the needle around the blue yarn (without entangling it) and under the white yarn



pull the white yarn up with the blue yarn in front of the loop





This is what the 3 methods look like in comparison



edge of method A – purled stitches and there is a line of the contrast color along each side



edge of method B – twisted knit stitches and colors are divided on each side



edge of method C: knit stitch edge and seperate colors on each side

You see, the 3 methods result in 3 different looks.

Method A:

  • is not very flexible, but sturdy
  • has a line of the other color at the buttom
  • has a purl stitch edge

Method B:

  • is more flexible than A and a little bit sturdier than C
  • both colors are divided on each side
  • has twisted knit stitches edge

Method C:

  • is very flexible, but not as sturdy as A&B
  • both colors are divided on each side
  • has knit stitch edge

Personally I tend to use method C for scarfs and accessories, but I would choose method B for things that get in action at the edges like pullovers, bags. I for myself don’t like the method A for it’s different colored line on each side, but this could be used as an element of design, too. There are certainly more ways to cast on for double knitting. Some people cast on with one color only and switch to double knitting in the second row/round. This results in a one colored edge on both sides. Whatever cast on you use, it is important to choose a rather flexible one, because double knit fabrics are quite flexible, too.+
