The foundation double crochet stitch (FDC) is a great way to start your next crochet project when working with double crochet stitches.

The FDC creates a chain stitch and a double crochet in the same stitch, which is why it is often referred to as the chainless foundation double crochet or the double crochet foundation chain.

The steps for this stitch are quite simple, and once you understand the basics, it is easy to crochet. So let’s dive into this foundation double crochet tutorial.

Find both photo, video & written instructions below.

What is the Foundation Double Crochet

The foundation double crochet is one of the chainless foundation stitches.

Crocheters often come across it when starting crochet projects, where the chains and double crochet stitches are worked at the same time as the first row of a pattern.

This is a great way to get a more stretchy foundation row, compared to crocheting the foundation chains first, then working the double crochet row separately.

The stretchy edge you get is great in many instances, such as when crocheting the neckline raglan garments and yoke sweaters, tops and cardigans. It’s also great as a cuff on sleeves and to create a hole for a button. But it is amazing for anything where you want a stretchy fabric.

Another bonus is the fact that it can make the edge more even and easier to block for projects like blankets.

The steps of the Foundation Double Crochet Stitch:

  1. Chain 4.
  2. Yarn over. Insert hook into 4th chain from hook, pull up a loop. Yarn over and pull through first loop (making the chain). *Yarn over and pull through 2 loops*, then repeat from *to* once.
  3. Yarn over. Insert hook into previous chain you made*, pull up a loop, yarn over and pull through first loop (making the chain). *Yarn over and pull through 2 loops*, then repeat from *to* once.
  4. Repeat step 3 until you’ve made enough stitches**.

*It should look like you go through a resemblance of a normal stitch, with 2 strands of yarn.

*4th chain in step 1 makes 1 stitch, step 2 makes 1 stitch & every time step 3 is repeated you make 1 stitch.

Materials Needed

To crochet the foundation double crochet you can use any crochet hook size and yarn. If you’re following a crochet pattern, use the crochet hook and yarn suggested.

Foundation Double Crochet Chart Symbol

The foundation double crochet chart symbol is related to the double crochet (dc) and chain (ch) stitch chart symbols.

It is a “T” with one line across it representing the yarn over you do when you crochet a double crochet, but also has a oval circle representing the chain stitch.

It will be turned in the direction it will lay in your finished crochet work.

Foundation Double Crochet FAQ

How do you replace chains with foundation double crochet?

To replace regular chains with the foundation double crochet on a project where the first row is double crochet stitches, you start the crochet project with three less foundation double crochet than the number of chains the pattern calls for as the first dc stitch row. Then you continue the crochet pattern as usual on the second row.
This is because you usually start in 4th chain (4th ch) from hook when crocheting the first double crochet row. Note that in some cases this could be the 3rd chain (3rd ch), then you will start with 2 less foundation double crochet.

Is the Foundation Double Crochet Difficult?

Some find the foundation half double crochet difficult and they may need to try it, frog (rip it out), and try again a few times before they get it. But everyone love the foundation double crochet once they get the hang of it.

Can you crochet foundation stitches on pattern using any basic stitch?

Yes, you can crochet foundation stitches on any easy pattern using basic crochet stitches.

Why use a foundation double crochet?

The reason why you may want to use a foundation double crochet instead of regular chains is because it creates a more stretchy edge for your crochet project.
