The world of crochet is a rich tapestry of stitches, techniques, and terminology. For newcomers and even experienced crafters, certain abbreviations can appear as cryptic puzzles. One such term that frequently surfaces in crochet patterns and discussions is “BLO.” Understanding what BLO means is crucial for accurately interpreting patterns and achieving the desired fabric texture and structure. Far from being a complex concept, BLO is a straightforward yet impactful technique that can significantly alter the appearance and feel of your crochet projects.
Understanding the BLO Stitch
At its core, BLO is an abbreviation for “Back Loop Only.” This instruction dictates where the crochet hook is inserted when working a stitch, specifically into only one of the two loops that form the top of a previous stitch.
The Anatomy of a Crochet Stitch
To fully grasp BLO, it’s helpful to visualize the top of a crochet stitch. When you complete a stitch, such as a single crochet, half double crochet, or double crochet, it creates a “V” shape at the top. This “V” is actually composed of two distinct loops:
- Front Loop (FL): This is the loop that is closest to you as you work.
- Back Loop (BL): This is the loop that is furthest away from you.
When a pattern simply calls for a standard stitch (e.g., “sc” for single crochet), you are instructed to insert your hook under both of these loops. However, when the pattern specifies “BLO,” you are to insert your hook only under the back loop of the stitch from the previous row or round.
Why Use BLO? The Impact on Fabric
The seemingly minor adjustment of working only into the back loop has a profound impact on the resulting fabric. This technique effectively creates a small ridge or raised line on the side of the stitch that remains visible.
- Definition and Texture: Working BLO creates a more defined and textured fabric. The unworked front loops tend to lie flat against each other, giving the fabric a slightly ribbed or even knit-like appearance. This can add a beautiful visual interest and a tactile quality to your projects.
- Stretch and Drape: Projects worked entirely in BLO often have a different stretch and drape compared to those worked through both loops. The fabric can become less elastic and may hang more rigidly, which is desirable for certain items like baskets, sturdy bags, or structured garments.
- Flexibility: While working entirely in BLO changes the fabric significantly, you can also use BLO strategically within a pattern. For instance, a pattern might call for a few rows of BLO to create a specific edge or to transition between different stitch patterns.
Practical Applications of BLO
The BLO technique is not merely an academic detail; it’s a versatile tool that crafters utilize for a variety of functional and aesthetic purposes.
Creating Ribbing and Texture
One of the most common uses of BLO is to mimic the ribbed texture found in knitted fabrics. This is particularly effective when working with stitches like single crochet or half double crochet.
- Knitted Look: By consistently working through the back loop only, the unworked front loops from the previous row stack up, forming horizontal ridges that resemble the purl stitches in knitting. This is a popular choice for crocheters who desire a more refined, less “holey” look for their projects.
- Amigurumi: In amigurumi (the art of crocheting stuffed toys), BLO is frequently used for creating the distinct shapes and seamless transitions between body parts. For example, working BLO for the base of a head can create a flatter, more defined edge that can be easily sewn to the body. Similarly, it’s used to create legs and arms that maintain their shape.
- Hats and Headbands: The ribbed effect of BLO is excellent for hats and headbands, as it allows the finished item to hug the head snugly and comfortably. The slight rigidity also helps the brim of a hat maintain its shape.
Defining Edges and Seams
BLO is also instrumental in creating clean, defined edges and in preparing fabric for seaming.
- Stable Edges: When you need a very stable and neat edge for a project, such as the top edge of a bag or the opening of a garment, working in BLO can provide this structure. The resulting edge is less likely to curl or stretch out of shape.
- Preparing for Seaming: In patterns where pieces are crocheted flat and then seamed together, working the outer edges in BLO can create a slightly raised edge that is easier to sew through. This makes the seaming process neater and the finished seam stronger. For instance, if you’re crocheting two panels for a sweater, working the side edges in BLO will give you a defined line to follow when you whipstitch or mattress stitch them together.
Working in Rows vs. Rounds
The application of BLO can differ slightly depending on whether you are crocheting in rows or in rounds.
- Working in Rows: When working back and forth in rows, you will typically alternate between working the stitch through both loops (on the “right side” of the fabric) and working the stitch in BLO (on the “wrong side”). This alternating pattern is what creates the distinct ribbing effect. If you were to work BLO on every single stitch in every row, the fabric would lean significantly in one direction.
- Working in Rounds: When working in rounds, the concept is more straightforward. If a pattern calls for BLO in rounds, you will simply insert your hook into the back loop of each stitch around the entire round. This is commonly seen in the base of amigurumi or when creating seamless cylindrical objects.
Common Abbreviations Related to BLO
While BLO is the most common abbreviation, you might encounter variations or related terms that further refine how you work the back loop.
BLO vs. FLO
Just as there’s BLO (Back Loop Only), there’s also FLO (Front Loop Only). Understanding the contrast is key.
- FLO (Front Loop Only): Working in FLO means inserting your hook only into the loop closest to you. This technique is often used to create a visible stitch line on the opposite side of the fabric, which can be utilized for specific decorative effects or to prepare for joining subsequent rounds of stitches in a particular way. For example, a pattern might instruct you to work in FLO for a few rounds to create a base for attaching a decorative element later.
- Contrast: The primary difference is the location of insertion. BLO creates a raised texture on the side of the stitch facing away from you, while FLO creates a raised texture on the side facing you. The choice between BLO and FLO depends entirely on the desired aesthetic outcome of the project.
Other Variations
Occasionally, you might see slightly more specific instructions that build upon the BLO concept.
- “Working in the 3rd Loop” or “Working in the Back Ridge”: For certain stitches, like the half double crochet, when worked in rows, the process of working BLO can create a “third loop” or “back ridge” that lies parallel to the front edge of the stitch. Some patterns may specifically refer to working into this third loop, which is essentially the same as working BLO for a standard hdc in rows. This third loop is the loop that was the back loop of the stitch in the previous row, but now it’s positioned behind the V formed by the current stitch.
Tips for Working BLO Effectively
Mastering the BLO technique is a valuable skill that can elevate your crochet projects. Here are some tips to ensure you’re working it effectively.
Maintaining Consistency
The most crucial aspect of working BLO is maintaining consistency. If you’re aiming for a ribbed effect, every stitch in that designated section must be worked into the back loop only.
- Pay Close Attention: Before starting a row or round marked for BLO, take a moment to identify the front and back loops of the previous stitches. This is especially important in the initial rows of a project or when transitioning from a standard stitch to BLO.
- Use Stitch Markers: If you’re working in rounds and find yourself losing track of where you are or struggling to distinguish the back loops clearly, consider using a stitch marker to mark the beginning of your round. This can help maintain your orientation and ensure accuracy.
Understanding Your Yarn and Hook
The interaction between your yarn and hook can influence how easily you can work BLO.
- Yarn Weight and Fiber: Finer yarns or those with a bit more grip might make it slightly easier to separate the loops and insert your hook into the back loop only. Smoother, silkier yarns might require a bit more finesse.
- Hook Size: Ensure your hook size is appropriate for your yarn. A hook that is too large might cause the loops to become too loose and difficult to manage, while a hook that is too small could make it physically challenging to insert into the back loop.
Practicing BLO
Like any new technique, practice makes perfect.
- Swatches: Before diving into a large project that relies heavily on BLO, crochet a few small swatches. Experiment with different stitches (single crochet, half double crochet, double crochet) in BLO. This will help you get a feel for the tension, the look of the fabric, and how to maintain consistent tension.
- Identify the “Ridge”: As you practice, focus on the small ridge that forms on the side of the stitch. This visual cue will help you confirm that you are indeed working into the back loop only.
BLO: A Stitch of Subtle Power
The seemingly simple instruction to work a stitch “back loop only” unlocks a world of textural possibilities in crochet. From creating the elegant ribbing of a cozy hat to forming the sturdy structure of a handcrafted basket, BLO is a technique that every crocheter should have in their repertoire. By understanding the mechanics of the stitch and practicing its application, you can imbue your projects with a new level of sophistication, definition, and visual appeal. So, the next time you encounter “BLO” in a pattern, embrace it as an opportunity to explore the subtle yet powerful artistry that crochet offers.
