Mastering How To Increase Knitting: Precision Techniques For Perfect Shaping

Increasing in knitting is the fundamental process of adding stitches to a row to create width, shaping, or decorative patterns within a garment. Achieving professional results requires selecting the appropriate increase method based on the desired visual aesthetic, whether you require an invisible integrated increase or a visible decorative stitch.

Essential Preparation and Technical Prerequisites

Before beginning any project requiring increased stitch counts, you must ensure your toolset and foundational knowledge are aligned with the pattern requirements. Proper preparation minimizes dropped stitches and uneven tension, which are the primary causes of structural failure in knitted garments.

• Tooling Requirements:
  
  
  • Needles: Matching the diameter (mm) to your yarn weight—typically ranging from 2.0mm for fingering weight to 8.0mm or larger for bulky weight yarns.
  • Stitch Markers: Essential for tracking the location of increases, especially in complex lace or sweater yoke constructions.
  • Yarn Tension Guide: Ensuring your gauge swatch matches the pattern specifications is mandatory before commencing the work.
• Prerequisite Competencies:
  
  
  • Proficiency in reading standard knitting abbreviations (e.g., M1L, M1R, YO, KFB).
  • Understanding the difference between mirrored increases (Left-leaning vs. Right-leaning).
  • Ability to maintain consistent yarn tension across multiple increases to prevent holes or puckering.
• Operational Benchmarks:
  
  
  • Duration: Dependent on project complexity; expect 5–10 minutes per row for intricate increases.
  • Budget: Minimal; primarily the cost of project yarn and required needle sizes.

Technical Execution of Knitting Increases

Step 1: The Make One Left (M1L) Increase

The M1L is a lifted, left-leaning increase that creates a seamless, nearly invisible join. It is the industry standard for sweater raglan shaping.

1. Identify the horizontal strand of yarn connecting the stitch you just worked and the next stitch on the left needle.
2. Using the tip of your left needle, pick up this strand from the front to the back.
3. Insert your right needle into the back loop of this newly placed strand.
4. Wrap your yarn and pull it through, creating a new, twisted stitch.

Pro-Tip: Always pick the strand up from the front to the back to ensure the resulting stitch is twisted, which prevents a visible hole from forming in the fabric.

Step 2: The Make One Right (M1R) Increase

The M1R is the mirrored counterpart to the M1L. When used in conjunction, these two methods create a clean, V-shaped decorative line.

1. Locate the same horizontal strand between stitches.
2. Using your left needle, pick up the strand from the back to the front.
3. Insert your right needle into the front loop of this strand.
4. Knit into the stitch as usual, ensuring the loop is twisted to close the gap.

Step 3: The Knit Front and Back (KFB) Increase

The KFB, also known as the Bar Increase, is a visible, structural increase that leaves a small horizontal bar at the base of the new stitch. This is ideal for top-down construction or areas where a decorative edge is desired.

1. Knit into the front loop of the stitch as you would normally, but do not drop the original stitch off the left needle.
2. Bring your right needle to the back of the work.
3. Knit into the back loop of the same stitch.
4. Drop the original stitch off the left needle.

Step 4: The Yarn Over (YO) Increase

The YO is primarily used in lace knitting because it creates an intentional, decorative eyelet. It is technically categorized as a decorative increase rather than a shaping increase.

1. Bring the working yarn to the front of your needles between the two needles.
2. Bring the yarn over the right needle to the back.
3. Knit the next stitch as indicated by the pattern. This action creates a new loop on the right needle without working into an existing stitch.

Technical Comparison of Increase Methodologies

Troubleshooting Common Knitting Increase Errors

• Root Cause: Holes appearing where increases should be seamless.
  
  
  • Fix: Ensure you are twisting the yarn strand. If the strand is not mounted such that the needle passes through the back loop, the base remains open, creating a hole. Always verify the orientation of the strand on the needle before knitting into it.
• Root Cause: Tension variation causing "ladders" or loose stitches.
  
  
  • Fix: Maintain a slightly firmer tension when working the increase itself. If using M1L/R, pulling the working yarn slightly after placing the strand on the needle can compensate for the slack inherent in lifted increases.
• Root Cause: Incorrect stitch count in the subsequent row.
  
  
  • Fix: Implement a "count check" every 10 rows. Use stitch markers to isolate the area where the increases occur to ensure you are adding the required number of stitches per row without accidentally working an increase twice in the same position.

Frequently Asked Questions

What is the most invisible way to increase stitches?

The M1L (Make One Left) and M1R (Make One Right) are widely considered the most invisible methods. Because they are lifted increases that incorporate the yarn bar between stitches, they blend seamlessly into the knitted fabric without leaving decorative holes or extra bars.

How do I know when to use an M1L versus an M1R?

You use M1L and M1R to create a directional flow in your knitting. In a raglan sweater, you use M1L on the left side of the marker and M1R on the right side to ensure the increases lean away from the center, creating a symmetrical, professional appearance.

Is the Knit Front and Back (KFB) increase considered a bad habit?

The KFB is not a "bad" habit, but it is a distinct technique that leaves a noticeable horizontal bump. It is excellent for structural shaping where strength is needed, but should be avoided in smooth, stockinette-focused designs where you prefer an invisible transition.

Does a Yarn Over increase change the stitch count?

Yes, a Yarn Over increases your stitch count by one, but it also leaves a decorative hole. It is the primary tool in lace knitting for creating openwork designs and should not be used in solid fabrics where holes are undesirable.
