Sometimes there are patterns that call for a foundation single crochet (FSC) row to start the project. I had no idea how to do the FSC row and would either attempt to do 2 rows of single crochet or give up and look for another similar pattern that didn’t call for it. But after seeing FSC so many times, I decided to learn how to do it myself!

The main use for a foundation row is to help start a project with a steady and untwisted base row. Essentially the foundation single crochet stitch creates two layers of single crochet right on top of each other at the same time.

This post will go over the basic foundation single crochet stitch.

Step 1: Slip stitch yarn onto hook.

Step 2: Chain 2


Step 3: Insert hook in the middle of the first chain stitch. Be sure to have 2 strands of the chain stitch facing toward you and the remaining one strand facing away from you on the back of the work. This will look like 3 stitches on the hook, but treat the 2 strands of yarn from the original chain as one stitch and always work with them together.


Step 4: Yarn over and pull through the 2 stranded initial chain stitch (the first 2 strands on the hook). At the end of this step, you will now have 2 stitches with 1 strand each.


Step 5: Yarn over again and pull through the top stitch already on the hook. At the end of this step, you will still have 2 stitches with 1 strand each.

Step 6: Yarn over once more and pull through both stitches on the hook. After this step you will have only one stitch left on the hook. The work will look triangular at this point which is completely normal.


Step 7: Push hook through the center of the stitch directly to the left of where the yarn is coming out of the project. This will be identical to Step 3 to make sure to have the 2 strands of the stitch on top towards you and have the remaining 1 strand facing away from you on the bottom of the work. Treat the 2 strands as one single stitch.


Step 8: Yarn over and pull through the 2 strands that make up the single stitch that is already on your hook just like Step 4.


Step 9: Yarn over again and pull through top stitch on hook only just like Step 5.


Step 10: Yarn over once more and pull the new yarn over through the 2 stitches on the hook just like Step 6.

Repeat these steps until you have the desired length of a Foundation Single Crochet row. You can start to see the 2 single crochet rows forming as one unified foundation chain the longer the work gets.

Once you are done with the foundation row, just chain and turn your work to begin on the next row.

Chain 1 and turn if you are going to only use single crochet on the next row. Chain 2 and turn if you are going to use half double or double crochet.


For this tutorial, I used a hook that was a little too big for the yarn I was working with and as a result, the stitches are a little further apart and they are easier to see. When using the correct sized hook, expect the stitches to be a bit closer together and not as large and lacy looking.

Here you can see the 4 rows of my completed work.

Row 1 is the Foundation Single Crochet row.

Row 2, 3, and 4 are all double crochet.


You can see the difference in the height of the stitches from the foundation single crochet row to the double crochet row.

The FSC stitch is especially common in smaller finished projects like hats and scarves. It makes sure the starting chain is flat and sized correctly without much stretching or warping and kept free from twisting (I think we all have ended up with a möbius scarf at one point or another lol)! Please note that this tutorial uses the US terms for crochet.

I will be posting a video soon on my YouTube channel DJ DIY to show the entire process of creating an FSC row.

The project that convinced me to learn how to use FSC is the Persia Lou Black Cat Slouch Hat pattern. Give it a try and post your photos or any questions in the comment section below!

Have a great day and thanks for stopping by 🙂
