A crochet stitch has a top that usually looks like a small V, made of two strands called the front loop and back loop. Learning to spot these loops—and distinguish them from the active loop on your hook—helps you place stitches correctly, count your work, and follow beginner patterns with confidence.
You do not need to memorize every crochet term before making something lovely. Grab a light-colored practice swatch, take a closer look at one stitch, and let’s get familiar with the little details that make a big difference.
What are the main parts of a crochet stitch?
Most basic crochet stitches have a V-shaped top and a body beneath it. The two strands of the V are the loops you will usually work under, while the body helps you recognize the stitch and understand its height.
Here is a simple stitch-anatomy guide using US crochet terminology:
Stitch part |
Where to look |
Why it matters |
|---|---|---|
Front loop |
The strand of the top V closest to you as you work |
Working under this loop alone changes the fabric’s texture |
Back loop |
The strand of the top V farthest from you as you work |
Working under this loop alone can create ridges and ribbed effects |
Stitch body or post |
The section below the top V |
Helps you identify stitches; some techniques work around the post |
Active loop |
The loop currently sitting on your hook |
Stays on the hook between stitches and does not count as a completed stitch |
The V can be easier to see from above than from the front of your fabric. Tilt the top edge toward you and gently spread the stitches without stretching them out of shape.
How do you find the front loop and back loop?
Hold your work in its normal crocheting position and look down at the top edge. The strand nearest you is the front loop, and the strand farther away is the back loop.
These names describe the loops’ position relative to you as you work, not a permanent front and back of the project. When you turn your work to begin another row, identify the loops again from your new working position.
To practice finding them:
Make or pick up a small swatch of single crochet.
Locate the V at the top of the next stitch you would work into.
Touch the closer strand with the tip of your hook: that is the front loop.
Touch the farther strand: that is the back loop.
Slide your hook under both strands to see the usual insertion point.
Helpful tip: Smooth, light-colored yarn makes stitch details easier to see than dark, fuzzy, or highly textured yarn.
What is the difference between the active loop and stitch loops?
The active loop sits on your hook, while the front and back loops belong to a stitch already made. A yarn over is different again: it is yarn wrapped over the hook as part of making a stitch.
These terms often appear together, but they are not interchangeable:
Active loop: The working loop you keep on your hook between completed stitches.
Stitch loops: The strands you insert your hook under in the previous row or round.
Yarn over: The action of bringing the working yarn over the hook.
Drawn-up loop: A new loop pulled through a stitch or space during a stitch-making step.
For example, in a single crochet, you start with one active loop, insert your hook into the next stitch, yarn over, and pull up a loop. You now have two loops on the hook; yarn over again and pull through both to finish the stitch.
The single loop left on your hook is your new active loop. Do not count it as an extra completed stitch when checking your row.
Where should you insert your hook for a basic stitch?
For most basic stitches worked into a previous row, insert your hook under both top loops unless the pattern directs otherwise. Working under both loops is the standard placement for an ordinary single crochet, half double crochet, or double crochet in that situation.
Pattern instructions take priority. You might instead be asked to work into a chain space, around a post, between stitches, or under just one loop.
For a standard single crochet worked in rows:
Find the next stitch’s top V.
Insert your hook from front to back under both strands of that V.
Yarn over and pull up a loop through the stitch.
Yarn over and pull through both loops on your hook.
Look at the new V you have just formed at the top of your stitch.
Notice the distinction: “Under both loops” describes where you insert the hook. “Pull through both loops on the hook” describes a later step in completing a single crochet.
What do front loop only and back loop only mean?
Front loop only means inserting your hook under just the nearer strand of a stitch’s top V. Back loop only means inserting it under just the farther strand, leaving the other strand unworked.
These small placement changes can give familiar stitches a different look and feel.
What happens when you crochet in the front loop only?
Working in the front loop only, often abbreviated FLO, leaves the back loop unworked. The unworked strand can form a visible line on the opposite side of the fabric; the overall effect depends on your stitch and pattern.
To try it, insert your hook under only the nearer strand of the next V. Complete the stitch normally after that insertion.
What happens when you crochet in the back loop only?
Working in the back loop only, often abbreviated BLO, leaves the front loop unworked. Repeated rows of back-loop-only single crochet commonly produce a ridged fabric used for ribbed-looking bands and other textured details.
Insert your hook under only the farther strand of the next V, then finish the stitch as usual. Identify that farther strand again after each turn rather than relying on which side of the project faces you.
Read the abbreviation key: Some patterns use FL or BL instead of FLO or BLO. Always check the designer’s definitions before beginning.
Are the loops of a foundation chain different?
A foundation chain has V-shaped links on one side and small bumps along the back. It does not have the same stitch body as a row of single crochet, so finding your insertion point can feel different at first.
You may encounter instructions to work into a chain loop, under two strands, or into the back bump. Follow the pattern’s preferred method consistently across the foundation row.
To recognize the chain:
Lay a short chain flat and look for the row of V-shaped links.
Turn it over gently to find the small bumps running along its back.
Keep track of the active loop on your hook; it is not one of the chains you count.
Check which chain the pattern tells you to start in before inserting your hook.
Working into the back bumps can leave a neat row of Vs along the lower edge. It is a useful option, but it is not a universal requirement for every project.
How can you practice recognizing crochet loops?
Make a small single-crochet swatch with sections worked under both loops, front loop only, and back loop only. Comparing them in the same piece helps you see how hook placement changes the surface of the fabric.
You will need smooth, light-colored medium-weight yarn, a compatible crochet hook recommended on the yarn label, scissors, and a locking stitch marker if you have one. Choose a hook that lets you work comfortably without forcing it through tight loops.
Tool safety: Handle scissors and yarn needles carefully, store sharp tools away from children and pets, and supervise young learners. Wear appropriate personal protective equipment for any tools that require it and follow manufacturers’ instructions. Take breaks and stop if crocheting causes pain, numbness, or tingling.

Chain 13. Keep the chains relaxed and even.
Make row 1. Single crochet in the second chain from the hook and in each remaining chain for 12 stitches. Use one consistent chain-insertion method.
Practice both loops. Chain 1 and turn. Single crochet under both top loops of each stitch across. Repeat for one more row. The chain 1 does not count as a stitch in this exercise.
Practice front loops. Chain 1 and turn. Work 12 single crochets in the front loops only. Repeat for one more row.
Practice back loops. Chain 1 and turn. Work 12 single crochets in the back loops only. Repeat for three more rows.
Compare your sections. Look for unworked strands, surface lines, and changes in flexibility. Count 12 stitches after every row.
Place a marker in the first stitch of each row if you have trouble finding it after turning. Move the marker into the new first stitch as you begin the next row.
What common loop mistakes should beginners watch for?
The most common problems are accidentally catching just one top loop, splitting the yarn, or mistaking the turning chain for a stitch. Checking your hook placement and stitch count every row makes these mistakes easier to catch early.
Accidentally working under one loop: If your pattern expects both loops, look for both strands resting above the hook before drawing up yarn.
Splitting a strand: Insert the hook beneath the yarn strand rather than through its individual fibers. Loosen your tension slightly if insertion feels difficult.
Missing the last stitch: Mark the first stitch before turning so you can recognize it as the last stitch on the following row.
Adding an extra edge stitch: Check whether the turning chain counts as a stitch. In the practice exercise above, it does not.
Confusing the back loop with another strand: Some stitches, especially half double crochet, have an additional strand commonly called a third loop. Do not substitute it for the top back loop unless instructed.
If a row looks different, pause before pulling it out. An unexpected ridge may simply mean you worked into one loop instead of two—a useful clue as you learn to read your crochet.
What do beginners often ask about crochet loops?
You do not need a new stitch for every new texture: changing which loop you work into can transform a stitch you already know. These answers clarify a few details that often cause confusion during early projects.
Does the loop on the hook count as a stitch?
No. The active loop is not counted as a completed stitch or a foundation chain. Count the finished stitches or chain links below it.
Should you always crochet under both loops?
Work under both top loops for ordinary stitches into a previous row unless the pattern specifies another placement. Foundation chains, spaces, post stitches, and special textures may use different insertion points.
Are front loop and back loop instructions different for left-handed crocheters?
The basic definitions stay the same: the front loop is nearest you, and the back loop is farthest away. Left-handed crocheters generally work across the fabric in the opposite direction, but these loop names still describe position relative to the person crocheting.
Why does your crochet have a horizontal ridge?
A ridge may be made by loops left unworked when you crochet into only one top loop. Check your pattern and compare the row with neighboring rows; the ridge may be intentional rather than a mistake.
How can you keep building your crochet confidence?
Start by recognizing the top V, finding its two loops, and checking where your hook enters each stitch. A few short practice sessions can make these details feel much more familiar before you move on to a larger project.
Keep your swatch nearby as a handy reference. When a pattern says “BLO” or “work under both loops,” you will have a real example to look at and touch.
