How To Decrease In Crochet: The Ultimate Guide For Beginners & Beyond
Have you ever stared at a beautiful crochet pattern, only to feel a wave of panic when you read the words "decrease 2 stitches" or "sc2tog"? You're not alone. The how to decrease in crochet question is one of the most common hurdles for crocheters moving beyond simple rectangles. Mastering decreases is the secret key that unlocks shaping—it’s what transforms a flat scarf into a fitted hat, a cozy sweater, or a adorable amigurumi toy. This comprehensive guide will demystify every aspect of crochet decreases, from the absolute basics to advanced invisible techniques, ensuring you can tackle any pattern with confidence and create beautifully shaped projects.
Why Decreasing is the Secret Weapon of Crochet Shaping
Before we dive into the how, let's understand the why. Decreasing is a fundamental technique that allows you to reduce the number of stitches in a row or round. This simple action creates angles, curves, and tapered shapes. Without decreases, every crochet project would be a simple rectangle or square. Decreasing is the cornerstone of garment construction, enabling you to create armholes, necklines, waist shaping, and sock heels. It’s equally vital in amigurumi for sculpting heads, bodies, and limbs. By learning to decrease correctly, you move from following basic instructions to truly designing and understanding the architecture of your crochet work. It’s the skill that bridges the gap between a beginner and an intermediate crocheter.
The Building Blocks: Understanding Single Crochet Decreases (sc2tog)
The single crochet decrease, often abbreviated as sc2tog (single crochet two together), is the most fundamental decrease you’ll encounter. It’s the workhorse of shaping in projects worked in single crochet stitch, like many amigurumi and some blanket patterns. The goal is to take two stitches and combine them into one, effectively reducing your stitch count by one.
Step-by-Step: How to Work a Standard Single Crochet Decrease
- Insert your hook into the next stitch as if you were going to make a regular single crochet.
- Yarn over and pull up a loop. You now have two loops on your hook.
- Do NOT yarn over and pull through both loops yet. Instead, insert your hook into the very next stitch.
- Yarn over and pull up a second loop. You now have three loops on your hook.
- Yarn over and pull through all three loops on your hook. You have successfully combined two stitches into one.
Key Takeaway: The magic is in step 3. You must work the second part of the decrease into the next stitch immediately following the first without completing the first stitch. This creates a slightly visible, but structurally sound, decrease that leans to the right.
Common Pitfalls and How to Avoid Them
- Miscounting Stitches: Always count your stitches at the end of each row or round, especially when following a decrease sequence. Use a stitch marker at the start of the round.
- Loose Decreases: Ensure you pull your yarn through all loops firmly. A loose sc2tog can create a gap or hole in your fabric.
- Inconsistent Tension: Practice on a small swatch. Your decreases should match the tightness of your regular stitches.
Mastering the Double Crochet Decrease (dc2tog)
For projects in double crochet stitch—think sweaters, scarves, and many adult blanket patterns—you’ll need the double crochet decrease (dc2tog). The principle is identical to the sc2tog, but with the extra yarn overs and loops of the double crochet stitch.
The Double Crochet Decrease Breakdown
- Yarn over (this is the first part of your first dc). Insert hook into next stitch, yarn over, pull up a loop (3 loops on hook).
- Yarn over and pull through two loops (2 loops remain on hook). You have now completed the first part of your first dc, but not the final yarn over/pull through.
- Yarn over (this starts your second dc). Insert hook into the next stitch, yarn over, pull up a loop (4 loops on hook).
- Yarn over and pull through two loops (3 loops on hook).
- Yarn over and pull through all three remaining loops. Two stitches decreased into one.
Pro Tip: The dc2tog can look a bit bulkier than an sc2tog. Pay extra attention to pulling the final yarn over snugly to minimize its visibility.
The Invisible Decrease: The Professional's Secret for Amigurumi
If you’re making amigurumi, you’ve likely heard of the invisible decrease (inv dec). This technique is a game-changer, creating a smooth, tapered shape with virtually no visible stitch definition or gap. It’s perfect for the tops of heads, waists, and any area where you want a clean, polished look. The magic lies in where you insert your hook.
How to Work an Invisible Single Crochet Decrease
- Identify the "front loops only." Look at the top of your work. Each stitch has two loops: the one closest to you (front) and the one away (back). You will work only into the front loops for this decrease.
- Insert your hook under the front loop of the next stitch (as if to make a regular sc).
- Yarn over and pull up a loop (2 loops on hook).
- Without moving your hook, slide it over and insert it under the front loop of the following stitch.
- Yarn over and pull up a second loop (3 loops on hook).
- Yarn over and pull through all three loops.
The result? A decrease that mimics the slant of a regular single crochet stitch but is much tighter and neater. Practice this on a small swatch to get the feel for identifying and working into just the front loops. It’s an essential skill for serious amigurumi makers.
Decoding the Language: Reading Decrease Instructions in Patterns
Patterns communicate decreases in several ways. Understanding this "crochet code" is crucial for success.
- Abbreviations:
sc2tog,dc2tog,hdc2tog(half double crochet decrease). These are the most common. - Written Instructions: "Decrease 1 stitch," "Decrease 2 stitches," "Single crochet 2 stitches together." The number tells you how many stitches to combine. "Dec 2" means perform the decrease stitch (which inherently reduces by 1) twice in a row, reducing your count by 2.
- Charts: On crochet charts, a decrease is often represented by a symbol that covers two stitch positions, like a V-shape (for sc) or a T-shape (for dc) that spans two boxes.
- "Dec over next 2 stitches": This is another way to say
sc2togordc2tog.
Always check the pattern's "Special Stitches" or "Abbreviations" section first. Some designers may use a unique abbreviation or have a specific method (like an invisible decrease) they prefer.
Strategic Placement: Where and When to Decrease in Your Projects
Knowing how to decrease is only half the battle. Knowing where to place them is what creates intentional shaping.
- For Tapering (Amigurumi, Sleeves, Hats): Decreases are typically worked evenly spaced around the circumference of a round. A common formula is to decrease once every
(X)stitches. For example, in a round with 30 stitches, you might decrease every 6th stitch (30 ÷ 5 decreases = 6). The pattern will specify: "Round 5: [sc4, dec] repeat around (25 sts)." This means: single crochet in the next 4 stitches, then work a decrease. Repeat that sequence all the way around. - For Armholes & Necklines (Garments): Decreases are often placed at the sides of your work to create an opening. You’ll see instructions like "dec 1 st at each end of row" for several rows. This tapers the fabric inward from the armhole down.
- For Shaping Drape (Triangular Shawls): Decreases are worked along the edges, typically at the beginning and/or end of rows, to create a long, triangular shape.
Visualizing the Lean: Remember, a standard sc2tog or dc2tog leans to the right. If you need a decrease that leans to the left (for symmetrical shaping on both sides of a garment), you can work the decrease stitch starting from the second stitch of the pair instead of the first. However, most patterns are written assuming the standard right-leaning decrease on both sides, which creates a neat center point when worked from both edges.
Troubleshooting: Why Your Decreases Look Lumpy or Create Holes
Even with the right technique, decreases can sometimes misbehave. Here’s how to fix the most common issues:
- Holes or Gaps: This is usually caused by loose tension on the final yarn over of the decrease. Solution: Pull that final yarn over extra snugly. Also, ensure your hook size is appropriate for your yarn; a hook too large for the yarn weight can lead to gaps.
- Bulkiness: The standard decrease stitch is inherently a bit bulkier than a regular stitch. Solution: Use the invisible decrease for amigurumi or projects where smooth shaping is critical. For garments, blocking your finished piece can help even out minor bulkiness.
- Uneven Shaping: This happens when decreases aren't placed consistently. Solution: Use stitch markers! Place a marker in the first stitch of the round/row and count meticulously. For "dec every Xth stitch" patterns, place a temporary marker at each decrease location as you go to ensure even spacing.
- Your Fabric is Curling Inward Excessively: This can happen if you decrease too aggressively too soon. Solution: Double-check the pattern's stitch count. Sometimes, a few rows of straight (no decrease) work are needed before shaping begins to establish a stable base.
Beyond the Basics: Advanced Decrease Concepts
Once you’re comfortable with the fundamentals, you can explore more nuanced applications.
- Double Decreases (3 stitches together): Instructions like
sc3tog(single crochet 3 together) ordc3togreduce three stitches into one. The method is the same as a 2-stitch decrease, but you’ll insert your hook into a third stitch before pulling through all loops. These create sharper, more dramatic angles. - Combining Increases and Decreases: Advanced shaping, like in sweater sleeves or fitted garments, often uses a combination. For example, you might increase a few stitches for the bicep and then decrease to taper down to the wrist. Understanding both techniques allows you to follow complex shaping instructions.
- Decreases in Different Stitch Patterns: The principle remains the same, but the visual effect changes. A decrease in a bobble stitch or cable pattern requires careful attention to the established stitch pattern to maintain the design's integrity. Always refer to the pattern's specific instructions for these cases.
Putting It All Together: Your First Shaped Project
Now that you understand the theory, let’s apply it. A simple granny square triangle is a perfect first project for practicing decreases.
Pattern Concept:
- Start with a chain of 4, slip stitch to form a ring.
- Round 1: 6 sc in ring. (6 sts)
- Round 2:
[sc, dec]*repeat 3 times. (3 sts) You’ve just decreased from 6 to 3 stitches! - Continue working rounds, typically increasing on one side and decreasing on the other to create a triangle, or simply working even rounds to create a small, flat triangle motif.
Actionable Tip: Before starting your main project, always crochet a gauge swatch that includes the decrease rows. This ensures your tension is correct and the decreases look as intended. Count your stitches after every decrease row to catch mistakes early.
Frequently Asked Questions About Crochet Decreases
Q: Can I use a different hook size for decreases to make them neater?
A: It’s generally not recommended. Changing hooks mid-project creates inconsistent tension. It’s better to master the technique with your main hook and yarn. If gaps persist, try a slightly smaller hook for the entire project or focus on tightening your final yarn over.
Q: What’s the difference between a decrease and an "skip" stitch?
A: A decrease (sc2tog) actively combines two stitches into one, maintaining the fabric's structural integrity. Simply skipping a stitch (e.g., sl st in next st, ch 1, skip next st) creates a hole or opening, which is a different technique used for lace or lacy edgings, not for solid shaping.
Q: My pattern says "dec over next 2 stitches" but I only see one decrease symbol on the chart. Is that the same?
A: Yes, absolutely. "Dec over next 2 stitches" is the written instruction for the single decrease stitch (sc2tog/dc2tog). On a chart, one decrease symbol spanning two stitch boxes represents that single decrease stitch that reduces the count by one.
Q: Are decreases reversible? Can I undo them?
A: Technically, you can frog (rip out) your work back to before the decrease row. However, you cannot simply "un-decrease" a stitch in progress. The yarn structure is permanently altered. If you make a mistake, it’s best to carefully pull back to the beginning of the row containing the error.
Conclusion: Your Journey to Confident Shaping Starts Now
