Foundation Half Double Crochet (FHDC), Chainless Step-by-Step Guide
Foundation half double crochet (fhdc) is a chainless crochet technique that lets you create your starting chain and first row simultaneously. In this step-by-step tutorial, you’ll learn how to do foundation half double crochet easily and avoid tight or uneven starting chains. This crochet starting method is perfect for use on blanket patterns, clothing, scarves, and any pattern that starts with a half double crochet edge.


How to Do Foundation Half Double Crochet (Quick Guide)
Here is how to do fhdc in 6 steps:
- Begin with a slip knot on your hook. Yarn over and chain two stitches.
- Yarn over, then insert your hook into the first chain.
- Yarn over and pull up a loop (3 loops on your hook).
- Yarn over and pull through the first loop on your hook.
- Yarn over again and pull through all three loops on the hook.
- For the next stitch, yarn over, insert your hook into the chain portion of the previous stitch, pull up a loop, create the chain, and complete the half-double crochet stitch.
What is a Foundation Half Double Crochet?
Chainless half double foundation crochet stitches are just what they sound like. The chainless foundation stitch approach is a different way to begin a new crochet piece. You will not crochet a number of chains and then work your first row into these chains with this technique. Instead, you will make each chain and corresponding stitch at the same time.

Anyone who understands the basics of crochet will tell you that you must always begin your piece with a foundation chain and then add your chosen design. But there is another way to start your crochet borders without counting out that tedious long chain—chainless foundation half double crochet stitches!
This article will focus on the half double crochet foundation (fhdc). Fhdc is a variation of the foundation single crochet stitch (fsc) technique. The difference is that fhdc creates half double crochet stitches instead of single crochet stitches.

Foundation Half Double Crochet (Step by Step)
Do you want to start a new project without making that long chain? In these step-by-step instructions, you’ll learn why chainless half double foundations are a great way to start a crochet project.
All instructions are written in American crochet terminology.
- ch = chain stitch crochet
- sc = single crochet
- hdc = half double crochet
- fhdc = foundation half double crochet.

If you are working with British terminology, this same stitch would be called foundation half treble crochet. (fhtc)
Here is how to do a chainless half double crochet stitch:
1. First FHDC Stitch
- STEP 1 – Start with a slip knot, chain 2.

- STEP 2 – Yarn over, insert hook through the second chain from the hook.

- STEP 3 – Yarn over and pull through. (3 stitches on hook)

- STEP 4 – Yarn over and pull through the first loop on the hook. (This is your foundation row’s first chain.) (3 stitches on hook)

- STEP 5 – Yarn over and pull your hook through the three loops. The first fhdc has been created. Quick and easy!

2. Second Foundation Half Double Crochet
- STEP 6 – Yarn over and slip the hook through the additional “chain” created in step 4. The hook must be inserted into the bottom “v” of the chain.

- STEP 7 – Yarn over and pull through a loop. (Three loops on hook)

- STEP 8 – Yarn over and pull through the first loop on hook, resulting in a chain 1. Pull this chain up loosely. This is your foundation row’s next “chain.”

- STEP 9 – Yarn over and pull your hook through the three loops. The second fhdc is made.

3. Half Double Crochet Foundation Row
Steps 6 to 9 should be repeated until the desired row length is obtained. Be sure to concentrate on working a chain and then a half double crochet into each previous chain. It is easy to forget the chain part of the step!

Once you have worked that first row of half-double crochet stitches, you are ready to start with the stitch pattern of your choice for the rest of your crochet item.
Tips and Tricks for FHDC
One piece of advice is to not to pull your stitches too tightly so that your foundation half-double row doesn’t curl. To do this, after pulling up the initial loop in a stitch, the hook should be held perpendicular to the foundation row. This prevents the bottom of the row from being significantly tighter than the top, which leads to less curling overall.
As a second piece of advice, as you draw through the initial loop on your hook, try to make it lie to the left so that all of your stitches have the same appearance. It will want to lie that way naturally, but I’ve found that giving each stitch a light push with my thumb (also to the left) on the foundation row helps it turn out beautifully.
Why Use Foundation Half Double Crochet Instead of Chains?
- Because of chain counting errors, you end up having to start projects over and over.
- You find it boring to work the long chain and it is sometimes difficult to crochet into the beginning chain because those chain stitches can be tight!
- Instead of a smooth, straight edge, the first row of your project has an uneven base.
- You want the first row to be a little bit looser. Crochet chains are often too tight, but a foundation row without chains is much more flexible.
I’m sure all of you have been at chain number 189, concentrating carefully, counting, when someone walks in and starts talking to you! Extremely frustrating! You have lost the stitch count and must start all over again! Now you can learn a new technique that allows you to count stitches even if you lose your stitch count!
When to Use Foundation Half Double Crochet?
Most crochet patterns begin with a long line of chain stitches to form a starting chain, then return to work the stitches for the first row into that chain foundation. Chainless half double crochet foundation stitches, on the other hand, replace this entire process, allowing you to work your chain stitches and first row of stitches at the same time. It is excellent for finishing the edge of a garment, a large blanket, or anything else you choose to name.
The fhdc can be used on any project that starts with a row of half double crochet. The half double crochet stitch creates a crocheted cloth that is hole-free and sturdy. So if your project is a hdc project, this type of foundation row is ideal.
Fixing Common Fhdc Problems
- Edge too tight? Pull up the first loop higher before completing each stitch.
- Row curling? Keep the chain section loose and consistent.
- Hard to find chains? Use a stitch marker every 10 stitches.
- Uneven stitches? Slow down and focus on forming the chain first.
Foundation Half Double Crochet FAQs
Your fhdc row will always be one less than the specified starting chain (if using the traditional method). So, in the example below, “Ch 11” followed by a row of “hdc” got you 10 stitches (the first ch is your turning ch and does not count as a stitch). But, if you substituted a fhdc row for this, you would need to work 10 fhdc to reach the same stitch count.
A slight curve in this foundation row is normal, but if it’s curving more than it should, you can rectify it by pulling the first loop in Step 1 up nice and high. The curve is caused by the fhdc stitches’ chain being too short. If everything is done correctly, you should have a highly stretchy and quick start to any hdc project!
In general, the process of making foundation rows takes more time as your starting row. Because you are effectively working on two rows at the same time, each stitch requires an increased number of steps. Despite this, it will be helpful over the long run because you will be able to skip an entire row- what would have been the first row working into your foundation chain.
A half double crochet foundation row can give more stretchy edges than a row of chain stitches. This can be a good thing if you want to have a stretchy base, or it can make your project look wavy at the bottom if it’s too loose.

In Conclusion
That’s all there is to the foundation half double crochet stitch, sometimes known as fhdc. I hope you liked learning this interesting basic crochet stitch! Fhdc is not difficult to learn, but it may take a bit of practice to get the hang of it. Once you master the technique, you’ll find that it’s a useful skill to have in your crochet toolbox. Remember that any stitch may be used to create a foundation row following the same logic as the fhdc!
