Learning front and back loop crochet is probably the easiest way to take your projects from looking "homemade" to looking professionally finished. Most of us start out learning to shove the hook under both of those little strands at the top of a stitch, which is totally fine for basic blankets or scarves. But once you realize you can pick and choose which loop to work into, it's like a whole new world of texture opens up. It's a simple tweak that doesn't require learning a complex new stitch, yet it completely changes how the fabric behaves and looks.
If you've ever looked at a crochet hat and wondered how they got that stretchy, ribbed look that looks almost like knitting, you're looking at the power of loop manipulation. It's honestly a game-changer for everything from garment cuffs to amigurumi.
What are we actually looking at?
When you look at the top of a row of crochet, you'll see a series of "V" shapes. Normally, you'd insert your hook under both legs of that V. In front and back loop crochet, we're just being a bit more selective. The "front loop" is the one closest to you as you're holding your work. The "back loop" is the one further away, on the far side of the stitch.
It sounds almost too simple to matter, but the results are night and day. When you only work into one loop, the loop you didn't use is left sitting there on the surface of the fabric. This creates a visible horizontal line or ridge. Depending on which loop you choose and whether you're working in rows or rounds, those ridges can become decorative features or functional ribs.
The magic of Back Loop Only (BLO)
If you only ever learn one variation, make it the back loop only (BLO) technique. This is the secret sauce for making ribbing. If you crochet a series of single crochet or half-double crochet stitches into the back loops only, and you do this row after row, you get a fabric that is incredibly stretchy.
I remember the first time I tried making a beanie. I was just doing standard rows, and it was stiff and had zero "give." Then someone told me to try BLO. Suddenly, the hat had that bounce you expect from a store-bought knit cap. It's also great for the cuffs of sweaters or the bottom waistband of a cardigan.
One thing to keep in mind with BLO is that it makes the fabric a bit taller and thinner than standard crochet. Because you're only anchored to one half of the stitch, the fabric can stretch out more. This is great for drape, but if you're making something that needs to be super sturdy—like a heavy-duty tote bag—you might want to stick to the traditional "through both loops" method for the base.
Why you should try Front Loop Only (FLO)
Front loop only (FLO) is a bit of a different beast. It's not used for ribbing quite as often as BLO, but it's amazing for adding decorative elements. Since the back loop is left untouched on the "wrong" side of the work, you end up with a very smooth surface on the back and a slightly raised texture on the front.
I love using FLO when I'm working on amigurumi (those cute little stuffed creatures). If you're making a doll and you want to transition from the body to a skirt, you can work a row in the front loops only. This leaves the back loops available on the inside of the work, where you can later join yarn to start the legs. It creates a very clean "shelf" for the skirt to sit on.
FLO is also fantastic for "overlay crochet." You can leave those back loops open to come back to later with a different color of yarn, creating layers of texture that look way more complicated than they actually are.
Alternating loops for unique textures
Once you're comfortable identifying the loops, you can start mixing them up. One of my favorite textures is created by alternating front loop and back loop stitches across a single row. If you do a front loop dc (double crochet) followed by a back loop dc, you get a thick, pebbled texture that's almost like a seed stitch in knitting.
This is perfect for dishcloths or heavy winter blankets. It creates a fabric that's reversible and has a lot of "scrubbing" power if you're using it in the kitchen. Plus, it's just fun to do. It keeps your brain engaged because you have to remember which loop you're on, but it's not so hard that you can't watch TV while you do it.
Drape and movement
One of the biggest complaints people have about crochet is that it can be "stiff" compared to knitting. If you find your sweaters are feeling more like cardboard than clothing, front and back loop crochet can solve that.
By working in only one loop, you're essentially creating a hinge in the fabric. This makes the finished piece much floppier and more fluid. If you're making a lightweight summer shawl or a breezy top, try doing your double crochets in the back loop only. You'll be surprised at how much more the fabric moves and breathes. It also uses a tiny bit less yarn, which is a nice bonus if you're playing yarn chicken with a limited stash.
A few tips for success
When you're first starting out with front and back loop crochet, there are a couple of things that might trip you up.
- Mind your edges: It's very easy to accidentally lose a stitch at the end of a row when working in BLO. The last stitch can sometimes "lean" over, making it hard to see the back loop. I always recommend using a stitch marker on the first and last stitch of the row until your eyes get used to how the loops sit.
- Watch your tension: Since you're only pulling against one strand of yarn, it's easy to pull that loop too tight or too loose. If you pull too tight, the ridge won't look uniform. If you're too loose, you'll end up with little gaps or holes in your fabric. Try to keep a nice, even flow.
- Hook size matters: If you find that your BLO ribbing looks a bit "holy" (too many gaps), try dropping down a hook size. This keeps the single strand of yarn tight enough to close the gap while still maintaining that stretch.
Which one should you choose?
If a pattern doesn't specify, you should always go through both loops. But if you're free-handing something, think about what you want the end result to be.
- Need stretch? Go for Back Loop Only.
- Need a decorative ridge on the front? Go for Front Loop Only.
- Need a flat, thin fabric with lots of drape? Try alternating or sticking to one loop throughout.
- Need something sturdy and opaque? Stick to both loops.
Honestly, the best way to learn is just to grab a scrap of yarn and make a small swatch. Do five rows of standard crochet, then five rows of BLO, then five rows of FLO. You'll see the difference immediately. The BLO section will be much "taller" and springier, while the FLO might feel a bit flatter and show more of a horizontal line.
Getting creative with color changes
Another cool thing about front and back loop crochet is how it handles color changes. If you change colors at the start of a BLO row, the ridge left behind by the previous color creates a very sharp, clean line. It looks much tidier than a standard color change, which can sometimes look a bit jagged.
I've seen some beautiful blankets where people use this to create a "pinstripe" effect. By changing colors every two rows and working in the back loops, you get these beautiful pops of color that look almost like they're floating on top of the fabric.
Final thoughts
At the end of the day, front and back loop crochet is just another tool in your kit. It's not something you'll use for every single project, but once you know how to do it, you'll find yourself reaching for it all the time. Whether you're trying to make a hat that actually fits or you want to add a little bit of flair to a plain blanket, playing with loops is the way to go.
It's one of those techniques that feels like a "cheat code" because it's so easy to do but makes your work look so much more technical. So, the next time you're starting a new project, don't just default to the usual way. Try aiming for one loop and see what happens—you might just fall in love with the texture.
