How to Double Knit

Double knitting is one of the best knitting techniques. When you double knit, you create two layers which can result in some beautiful projects when you use multiple contrasting colors. You can also use the same color and end up with a finished project with two layers to keep you cozy. If you want to learn how to double knit, you have come to the right place.

What is Double Knitting

Double knitting is a knitting technique that creates two layers of fabric at the same time. It’s perfect when you want to create something extra warm with two layers like winter socks. Or if you need to make something with some protective features like an oven mitt.

Double knitting can also result in some beautiful reversible projects. Since you can double knit with two different colors, it can help you add beauty to your pieces.

It is somewhat of a slow technique, so just stay patient and take your time if you’re going to start double knitting.

Double Knitting Tips

Getting Started

Double knitting has two layers, so you will need twice as many stitches as normal.

Figuring out how many stitches to cast on is often a point of confusion for beginners who are new to double knitting. Many patterns leave out this detail.

All you need to do is count the number of stitches in the pattern and multiply it by two. This will give you the correct number of stitches.

How to Cast On

One of the easiest methods for beginners to start with is to learn the long-tail cast on. It’s a fast and easy way to get your stitches on your needle. Once you learn it, you’ll find it incredibly easy.

Flat or in the Round?

You can double knit flat or in the round. Double knitting in the round tends to be easiest though, so we recommend this method if you are a beginner.

How Do I Read a Chart?

Each square of a chart is one knit stitch on the front and a purl stitch on the back. A chart shows only one side and you will not see the back because it is the same. Watch the video below for more information on how to read double knitting charts.

Selvage Stitches

When double knitting you will want to have a pair of selvage stitches at each end. These edge stitches make a perfect closed edge where the fabric joins. Selvage stitches are the most popular for creating a nice edge.

Working Your Pattern

When double knitting the sides of your fabric will be in a stockinette stitch.

The basics of double knitting are k1, p1, k1, p1. Do not break this rhythm. Before every knit stitch you will need to bring the yarns to the back of the work, and before the purl stitches bring the yarns to the front. The key is to always move both yarns no matter which stitch you are creating.

When you move both yarns to the front and back for each stitch, each layer of the fabric is created. The knit stitch creates the fabric on the front side and the purl stitch creates the backside.

How to Bind Off

While holding both yarns together as one yarn, knit the first 2 stitches together. Then knit one stitch (the same color as the stitch), bind off one stitch, purl one stitch (same color as the stitch), and bind off again.

You simply repeat this process until there are two stitches left and knit them together.
