Shaping in flat, row-by-row crochet works differently than the circular increases and decreases used in amigurumi, and it’s easy to end up with a piece that widens or narrows unevenly if the shaping isn’t distributed and executed carefully. This guide covers how increases and decreases actually function in flat rows, building on our guide on why crochet projects get wider or narrower.
Why Flat Shaping Is Different From Circular Shaping
In circular crochet, increases and decreases are typically spaced evenly around a continuous round to maintain a symmetrical shape radiating outward. In flat rows, shaping instead controls the width of each row as you move up the piece, most commonly used for garment pieces like sleeves, necklines, or fitted sides, where the fabric needs to widen or narrow gradually along its length rather than around a center point.
Basic Increase Methods in Flat Rows
Working two stitches into one stitch. The simplest increase, this adds one extra stitch to a row by working a second stitch into the same base stitch a first stitch was already worked into.
Working an extra stitch at the row’s edge. For shaping that specifically widens one or both sides of a piece, an increase worked right at the beginning or end of a row (rather than somewhere in the middle) shapes the edge directly.
Adding an extra chain at the start of a row. In some patterns, an additional chain stitch at the beginning of a row, worked into as a stitch on the subsequent row, functions as an edge increase.
Basic Decrease Methods in Flat Rows
Working two stitches together (often written as “dec” or a specific stitch abbreviation like sc2tog). This combines two stitches into one, effectively removing a stitch from the row’s total count. The exact mechanics vary slightly by stitch type but generally involve leaving loops on the hook from two stitches before completing them together in one final pull-through.
Skipping a stitch at the row’s edge. For decreasing specifically at the edge, simply not working the last stitch (or working it together with the second-to-last) shapes the edge inward.
Keeping Shaping Symmetrical Across Both Sides
For pieces needing symmetrical shaping on both the left and right edges, like a sweater body narrowing evenly toward a waist, working the same increase or decrease at both the start and end of a row (rather than only one side) keeps the piece centered and balanced rather than drifting off to one side.
A practical approach: Work your edge shaping method at the very start of the row, complete the row’s main stitches, then mirror the same shaping method at the very end of the row before turning.
Distributing Shaping Across a Row Interior
Some patterns call for shaping distributed across the width of a row rather than concentrated only at the edges, which produces a different visual effect, spreading the width change more subtly throughout the fabric rather than creating a distinctly angled edge.
How to space it evenly: Divide your total row width by the number of increases or decreases needed, spacing them at roughly equal intervals rather than clustering them together, which helps avoid a lumpy or unevenly distorted result. The Craft Yarn Council’s crochet terminology reference is a useful resource for confirming standard abbreviations like sc2tog across different pattern sources.
Tracking Your Changing Stitch Count
Since shaping rows intentionally change your stitch count, it’s essential to know exactly what count to expect after each shaping row, comparing your actual count against the pattern’s stated number rather than assuming your shaping worked correctly by feel alone.
A useful habit: Keep a written note or use a row counter tracking both your row number and expected stitch count together, particularly for patterns with many consecutive shaping rows.
Common Mistakes to Avoid
- Working shaping only on one side of a row when a pattern calls for symmetrical shaping on both edges, resulting in a piece that drifts off-center.
- Clustering multiple increases or decreases too closely together when even distribution across the row was intended, creating a lumpy rather than smooth transition.
- Losing track of your expected stitch count across many consecutive shaping rows, allowing small errors to compound significantly.
- Confusing edge shaping with interior shaping when a pattern specifically calls for one or the other, producing a differently shaped result than intended.
Tips for Better Results
- Count your stitches at the end of every shaping row specifically, comparing against the pattern’s stated count for that exact row, since shaping rows are where errors most often creep in.
- Use a stitch marker to mark the intended location of an interior increase or decrease before working the row, removing the guesswork of counting to the right spot mid-row.
- Practice both increase and decrease techniques on a scrap swatch if either is new to you, building comfort with the motion before working them into an actual garment piece.
- Keep a simple written log of your row number and expected stitch count for patterns with extensive shaping, rather than relying purely on memory.
Frequently Asked Questions
What’s the difference between shaping at the edge versus shaping within the row? Edge shaping changes the row’s width specifically at its outer boundary, creating a distinctly angled or stepped edge, while interior shaping distributes the width change across the row’s body, producing a more gradual, less visually abrupt transition.
Why does my shaped piece look lopsided even though I followed the pattern? This usually indicates shaping was worked on only one side when symmetrical shaping on both edges was intended, or that the shaping wasn’t distributed evenly if interior shaping was called for.
How do I know if a decrease method is working correctly? Count your stitches immediately after the decrease row and compare to your pattern’s expected count. If the count matches, the decrease was executed correctly, regardless of how the stitch itself looks visually.
Can I substitute a different decrease method than what a pattern specifies? Generally yes, as long as the substitute reduces your stitch count by the same amount, though visual appearance can vary slightly between different decrease techniques, which may matter for patterns where the decrease is also a visible design element.
Is shaping harder to execute in taller stitches like double crochet compared to single crochet? Not inherently harder, though taller stitches can make a decrease’s structure slightly more visually complex to execute cleanly, since there are more steps and loops involved in combining two taller stitches into one.
