How To Carry Yarn Up The Side In Knitting: A Master Guide To Clean Selvedges

Carrying yarn up the side, also known as floating yarn, is a technique used to transport a non-working yarn color vertically along the edge of a project without cutting it, ensuring a seamless transition between stripes or color blocks. By twisting the working and non-working yarns at the start of every two rows, knitters maintain uniform tension and prevent long, loose floats that can snag or distort the fabric edge.

Essential Preparation and Edge Management Requirements

Successfully carrying yarn up the side requires an understanding of edge consistency and tension control. When knitting stripes, this technique saves time by eliminating the need to weave in dozens of ends, but it demands a methodical approach to ensure the edge remains elastic and professional.

• Essential Gear: Two or more balls of yarn in contrasting colors, knitting needles appropriate for your chosen gauge, and a tapestry needle for the final finishing.
• Mandatory Prerequisites: Proficiency in basic knit and purl stitches and a foundational understanding of stranded colorwork tension.
• Industry Standard: The "twist" technique is the gold standard for maintaining a clean edge. If the yarn is not twisted, the floats will become excessively long, causing the side of the fabric to pull in and pucker, which ruins the structural integrity of the garment's side seam.
• Time Benchmark: Adding this technique to your workflow adds approximately 5 to 10 seconds per row end, significantly reducing overall project finishing time by eliminating end-weaving.

Step-by-Step Execution for Vertical Color Carries

Step 1: Secure the Initial Color Transition

When you reach the end of the row where a color change is required, finish your final stitch in Color A. Instead of cutting Color A, let it hang at the side of your work. Begin your next row using Color B. By simply picking up Color B from behind Color A, you create a natural vertical link.

Step 2: The Twist Execution

The most critical part of this process occurs at the beginning of the subsequent row. When you return to the edge where the unused color is waiting, you must twist the two strands together. Bring the new color up from underneath the old, unused strand. This effectively "locks" the float of the unused color into the edge of the fabric.

Pro-Tip: Always carry the unused yarn on the inside of the work if possible, or maintain a consistent tension so the float is tight enough to avoid snagging but loose enough to prevent edge contraction.

Step 3: Managing Tension Across the Float

As you carry the yarn up, the strand will span two rows. Ensure that the unused yarn does not pull the edge stitches too tightly. A common failure is pulling the float taut, which effectively shortens the side of your work and causes the garment to ruffle or wave. Allow the float to sit flush against the fabric edge.

Warning: Do not carry a single color up for more than four to six rows. If you are working in wide stripes (greater than 1 inch), you must either cut the yarn or find a way to anchor the float into the seam edge to prevent excessive length.

Step 4: Finalizing the Selvedge Appearance

Once the project is complete, the carried yarn will appear as a series of small, vertical bars along the edge. Because these floats are integrated into the selvedge, they are easily hidden within the mattress stitch or the final garment seam.

Common Field Failures and Troubleshooting

• Failure 1: Edge Puckering or Pulling

  
  
  
  • Root Cause: The carried yarn is under too much tension, effectively acting like a drawstring along the side of the project.
  • Actionable Fix: Practice the "open stitch" technique where you pull the edge stitch slightly wider before beginning the next row to compensate for the yarn float length.

• Failure 2: Visible Gaps at the Color Change

  
  
  
  • Root Cause: The tension at the transition point is too loose, causing the previous color to "bleed" into the new color row.
  • Actionable Fix: Ensure the first stitch of every row is tightened firmly after the yarn twist is completed. This anchors the transition and closes the gap.

• Failure 3: Unintentional Snagging

  
  
  
  • Root Cause: The carried yarn float is too long, catching on needles or jewelry during the construction process.
  • Actionable Fix: If the stripes are very wide, consider catching the unused yarn in the middle of the stitch pattern every two rows to shorten the float length without fully weaving in the ends.

Frequently Asked Questions

Can I carry yarn up the side for every knitting project?

While ideal for stripes, this technique is not recommended for projects with very lacy or open edges, as the carried yarn will be highly visible. Use it primarily for seamed garments or projects where the edge will be bordered by an i-cord or picked-up stitches.

How do I hide the carried yarn if I am not seaming the piece?

If the edge will remain exposed, try to carry the yarn only on the wrong side of the work and keep the floats as short as possible. Alternatively, you can work an i-cord edge to enclose the carried yarn floats entirely within the finished border.

Is it better to cut the yarn or carry it?

Carry the yarn if you are alternating colors every two to six rows. If your stripes are wider than one inch, it is better to cut the yarn and weave in the ends to maintain the structural elasticity and aesthetic neatness of the fabric.

Will the carried yarn add too much weight to my project?

Generally, no. The added weight is negligible unless you are using a very thick or bulky yarn. For delicate lace or fingering weight projects, keep the floats loose to ensure the fabric retains its natural drape.
