How to Foundation Single Crochet (FSC) +Video

Save it Now, Make it Later!

Foundation single crochet (FSC) is a crochet technique that combines the foundation chain and the first row of single crochet into one step. Instead of making a long chain and then working back into it, foundation single crochet creates both the chain and the stitch simultaneously. FSC creates a stretchy, flexible edge that is ideal for scarves, blankets, garments, and other projects that begin with a row of single crochet stitches. It is also easier to count, easier to adjust, and often more comfortable to work than crocheting into a long foundation chain. This step-by-step tutorial will show you how to foundation single crochet, when to use it, and why many crocheters prefer it over a traditional chain foundation.

What is Foundation Single Crochet?

The Foundation Single Crochet (FSC) stitch is a mixture of the chain and single crochet stitches. It makes it simple to work a foundation row of single crochet stitches without first forming a large chain. FSC allows you to easily alter the length of your foundation row and is ideal for beginning a scarf, Afghan, or any large piece of crochet.

Foundation Single Crochet is also known as: FSC, FSC crochet, or single crochet foundation chain.

Let’s start with an explanation of what a single crochet foundation chain is. Most crochet patterns begin by working a long line of chain stitches to make a starting chain, then going back and working the stitches for the first row into that chain foundation. Instead, chainless foundation stitches replace this entire process, allowing you to work your chain stitches and initial row of stitches simultaneously! (Very exciting!)

Here’s an example of a short row of foundation single crochet. The top half of the stitch resembles a single crochet, while the bottom half resembles chains.

Do you want to skip that long chain at the start of a new crochet project? Then you’ll want foundation single crochet (FSC)! In these step-by-step instructions, you’ll learn why chainless foundations are such a great way to start a crochet project.

  • Insert hook into the second chain from the hook.
  • Yarn over and pull through a stitch. (The hook should now have two loops.)
Insert, YO and pull through
  • Yarn over and draw a stitch through only the first loop – there should still be two loops on your hook.Y
  • You have now completed the chain portion of the foundation single crochet.

  • Mark this chain, as this is the stitch where you will place your hook to begin the next foundation single crochet. After you have marked a few stitches, you will find you no longer need to do this.

2. Second Stitch

Here is how to do a foundation single crochet second stitch:

  • Put your hook into the previous stitch’s chain section – between the chain and the single crochet – to make the next FSC.
  • Your hook must go through BOTH loops at the top of the chain. Two strands should be on the hook’s left and one loop on the hook’s right.
Second stitch
  • Yarn over and pull a stitch through. (Your hook should now have two loops.)
2 loops on hook
  • Yarn over and draw a stitch through only the first loop – there should still be two loops on your hook. (This is the next chain part.)
  • Move the marker and mark this stitch.
Second stitch of fsc
  • Yarn over and pull through both loops on your hook to produce a single crochet. (Your hook should only have one loop.) This is the end of your next foundation single crochet stitch.

3. Repeat the Foundation Single Crochet Pattern

  • Insert your hook into the chain section of the previous stitch and repeat step 2 to produce the next foundation single crochet.
  • Continue until your single crochet foundation row reaches the correct number of stitches.

Now that you’ve completed your first single crochet foundation row of stitches, you may proceed with your pattern. Remember that what you just did counts as the first row of single crochet if your pattern doesn’t specify FSC stitches.

Foundation Single Crochet Notes

  • Skill Level: Confident Beginner
  • Abbreviation: FSC
  • Replaces: Foundation chain plus first row of single crochet
  • Texture: Flexible and stretchy
  • Best For: Blankets, scarves, garments, and adjustable-width projects
  • Special Feature: Creates the foundation chain and first row simultaneously

Foundation single crochet creates a cleaner, more flexible starting edge than a traditional foundation chain and is especially useful for projects that require stretch.

Tips and Tricks For Working FSC

Changing Hook Size – A single crochet foundation row can be more stretchy than a row of chain stitches. This can be a good thing, or it can make your project look bad if it’s too loose. One way to deal with this is to use a smaller hook for the foundation row.

Tail Position – Another thing to consider is whether your pattern cares about the right side and wrong side rows or where your beginning tail goes. When you do a row of chain stitches and then a row of single crochet back across, the tail you started with will be at the bottom left of a row that faces right.

Timing – It also takes longer to make FSC in crochet in general. You’re basically working on two rows at the same time, and each stitch takes more steps. However, it is worth it in the long run, as you will be skipping one whole row.

Foundation Single Crochet vs Foundation Chain

A foundation single crochet row can be used when a project calls for a row of single crochet stitches in the first row of work. If you don’t know your crochet gauge or need to adjust the size or fit of a design, you should probably start with an FSC. Even if the pattern calls for a specific amount of chain stitches, you can substitute foundation single crochet stitches.

Foundation Single CrochetFoundation Chain
Chain and stitch worked togetherChain worked first
Stretchy edgeCan be tight
Easy to adjust lengthHarder to adjust
Easier stitch countingRequires counting chains
Less curlingMore likely to twist

How to Substitute FSC

Assume a pattern instructs you to make 30 chain stitches. Then, beginning with the second chain from your hook, make one single crochet stitch in each chain stitch across, totaling 29 single crochet stitches.

To turn that into a chainless foundation, simply make 29 FSC stitches as the foundation. Then, turn your work and complete the rest of the pattern as indicated. So, if your gauge isn’t quite right, you can easily change the pattern. This gives you more control over your project.

Why Use Foundation Single Crochet Stitch?

But why bother learning a new stitch when you already know how to chain and single crochet? I’m going to explain why! There are quite a few reasons.

  • Working with FSC is easier than with a chain foundation.
  • Counting stitches is a lot easier. Nobody has ever said, “I enjoy counting chain stitches.” When you utilize FSC, you won’t have to count out 700 chain stitches twelve times to ensure you have the correct quantity.
  • The most appealing aspect of FSC is that, because the first two rows are virtually stitched together, you will only have to remove a few stitches if your initial count was incorrect.
  • It does not coil or twist like traditional single crochet.
  • This chainless single crochet foundation technique is ideal for crocheting garments that need a flexible edge.

Foundation Single Crochet FAQs

Is single crochet foundation the same as chain?

No. You can skip the first chain and work a row of single crochet (or double crochet or treble crochet), building the stitches out side by side as described before. Instead of making base chains or starting chains, you just make the number of foundation stitches required to begin your row.

Why is my single crochet foundation curling?

Too-tight stitches are one of the most common causes of crochet curling. This will also cause your crochet fabric to stiffen, resulting in curl. The best solution to this problem is to use a larger hook size.

When working in the round, how do you join a foundation stitch?

Slip stitch the first and end stitches together, just like when you are normally crocheting in the round. Then, using the yarn tail, join the bottoms of the last and first stitches together. The yarn tail is right there, and you will need to weave it in any case.

Are There Other Foundation Crochet Stitches?

There is also a foundation half double crochet stitch and a foundation double crochet stitch. They are all similar to each other and make stitches like their conventional counterparts. They are worked in exactly the same way, only substituting the taller stitches for single crochet. The tallest option would be the foundation double crochet row.
