What is a Foundation Single Crochet?
Foundation single crochet, often abbreviated as fsc or FSC, is a crochet stitch that allows you to simultaneously create a foundation chain and a row of single crochet stitches in one go. This versatile method is prized by both beginners and experienced crocheters alike, as it eliminates the need for separate foundation chains and provides a more flexible, elastic edge to your projects.
Setting up the foundation single crochet is remarkably simple, and it’s a breeze to transition from the first row to subsequent rows when using FSC. Additionally, the technique lends itself well to various crochet projects, making it an essential skill in any crocheter’s repertoire. Whether you’re crafting garments, accessories, or home décor items, mastering the foundation single crochet can elevate your crochet game and open up a world of possibilities.

Foundation Single Crochet Basics
Definition
The foundation single crochet (FSC) is a really useful stitch in the world of crocheting. Instead of starting with a traditional chain, the FSC combines the foundation chain and the first row of single crochet stitches into one step. This method creates a more elastic and structured base for your projects and simplifies the crocheting process. It also avoid the often fiddly step of crocheting into a foundation chain.
In UK crochet terms, the foundation single crochet (FSC) is referred to as a foundation double crochet (FDC). If you’re following a pattern, always check whether it is written in US or UK crochet terms.
Benefits
FSC provides a number of important advantages, including:
- Elasticity: Foundation single crochet stitches provide a more elastic or stretchy edge compared to traditional chains. This makes it an excellent choice for projects requiring a flexible edge, such as hats, socks, and garments. Unlike a traditional foundation chain, which often creates a tight and rigid edge, FSC provides a more forgiving foundation so that the finished piece is comfortable and easy to wear.
- Efficiency: FSC simplifies the crocheting process. By combining the foundation chain and the first row of single crochet, you save time and effort without sacrificing quality or appearance.
- Ease of use: The FSC stitch can be more comfortable to work into than a foundation chain, as the stitches are larger and better-defined. This can make it simpler to locate and insert your hook for the following row.
- Accuracy: Because the FSC combines the foundation chain and the first row of single crochet stitches, the stitches can be easier to count. This helps to reduce the risk of ending up with too few or too many stitches.
- Consistent gauge: Another notable advantage of foundation single crochet is the ease of achieving a consistent gauge. In crochet, the gauge refers to the number of stitches and rows within a specified measurement. Maintaining a consistent gauge is crucial for creating correctly-sized projects, and FSC offers an effective way to do so. The even tension throughout the foundation row helps maintain stitch accuracy and results in a uniform edge.
- Aesthetics: Foundation single crochet stitches create a clean, even edge that looks great on both sides of your work. This is particularly valuable for projects where both sides will be visible, such as scarves or blankets. FSC also allows the crochet piece to have a more streamlined appearance. Traditional foundation chains can sometimes create a noticeable seam or ridge, whereas FSC produces a cleaner, more professional-looking edge.

How to Crochet the Foundation Single Crochet (FSC) Stitch
Creating a Slip Knot
To start your foundation single crochet (FSC) project, you first need to create a slip knot. Here’s how:
- Take your yarn and make a loop, ensuring the tail end is behind the working yarn.
- Pull the working yarn through the loop to create a new loop.
- Insert the crochet hook into the new loop.
- Gently tighten the knot around your hook.
Now that you’ve created the slip knot, it’s time to move on to the next step of your foundation single crochet.
Crocheting Foundation Single Crochet
Setting up the first row of a foundation single crochet involves a few steps:
- Create the slip knot as above and chain two (ch 2). These two chains will serve as your starting point.
- Insert your hook into the second chain from the hook, yarn over (yo) and pull up a loop. You should now have two loops on your hook.
- Yarn over again and pull through the first loop on your hook. This creates a single chain and is the foundation for your first foundation single crochet stitch.
- Yarn over once more and pull through both loops on your hook, completing the first FSC stitch.
- To create the next FSC stitch, insert your hook into the previously formed chain space (at the base of the last stitch), yarn over and pull up a loop.
- Repeat steps 3-5 until you have the desired number of FSC stitches for your project, ending on step 4.
You have now successfully crocheted a row of foundation single crochet stitches.

Frequently Asked Questions
How does foundation single crochet differ from a traditional chain?
Foundation single crochet (FSC) is an alternative to using a foundation chain to start a crochet project. Unlike a traditional chain, which requires creating a series of chains first, then working single crochet stitches into each chain, FSC combines the chain and the single crochet stitch into one. This method creates a base row that is more flexible and easier to work with than a traditional chain foundation.
What is the purpose of using foundation single crochet?
The purpose of using FSC is to improve the foundation of a crochet project. Using FSC eliminates the need for a separate chain and single crochet row, making the process more efficient. This technique also provides increased flexibility, which is particularly useful for projects like garments that require stretch and elasticity.
How to start a foundation single crochet project?
- Create a slip knot and chain two.
- Insert the hook into the second chain from the hook.
- Yarn over and pull up a loop, creating a chain stitch.
- Yarn over and pull through both loops, completing the FSC stitch.
- For the next FSC stitch, insert the hook into the chain you just created.
