Preparation and Safety Guidelines

Tools Needed
  • yarn
  • needle
  • crochet hook (optional)
Safety Guidelines
  • Use a yarn that matches your project closely in color and weight for an invisible seam. A significant difference will make the seam more noticeable.
  • Work loosely! Tight tension can make it harder to weave the stitches invisibly and may result in a noticeable seam. Practice on a scrap of yarn first.
  • Avoid pulling the yarn too tightly when closing the seam. This can distort your fabric and make the seam appear bulky or uneven.

Step-by-Step Instructions

  1. Preparation

    • Align the first and last rows of your cowl or infinity scarf.
    • For a Mobius twist, give the scarf a half-twist before aligning the stitches.
    • Align the stitches of the first and last rows.

  3. Begin Slip Stitch Seam

    • Begin the slip stitch seam. You can choose to work through either the front or back loops to keep the seam less bulky. (Working with back loops is recommended.)
    • Insert your hook (or needle) through the first stitch on both sides, catching both loops of each stitch.
    • Yarn over and pull through all loops to secure the first stitch.

  4. Continue Slip Stitch Seam

    • Continue the slip stitch, inserting your hook through the back loops of each subsequent stitch on both sides. Yarn over and pull through.
    • Maintain a loose tension to avoid cinching the scarf.
    • Keep the stitches relatively wide and avoid inserting the hook into the same stitch twice.

Tips

  • Use back loops for a less bulky seam.
  • Keep the tension loose to prevent cinching the scarf.
  • Avoid inserting the hook into the same stitch twice to maintain a neat and even seam.

Common Mistakes to Avoid

1. Inconsistent Tension

Reason: Uneven tension throughout the seam creates a visible line or puckering.
Solution: Maintain consistent tension on both pieces of fabric while working the slip stitch.

2. Incorrect Slip Stitch Technique

Reason: Using the wrong slip stitch method (e.g., slipping stitches from the wrong side) leads to a noticeable seam.
Solution: Ensure you are consistently slipping stitches from the right side of the work, picking up only the back loop of each stitch.

FAQs

What kind of yarn is best for an invisible slip stitch seam?
While you can use most yarns, smoother yarns without excessive texture or fuzz will generally result in a cleaner, more invisible seam. Avoid extremely bulky or fuzzy yarns, as they can make it harder to achieve a truly seamless look.
What if I make a mistake? Can I easily fix it?
Don't worry! Minor mistakes are easy to correct. You can carefully unpick a few stitches with a crochet hook and re-try the slip stitch. For larger mistakes, it's often easiest to start again with that section of knitting, though you might have to frog back (rip out knitting) a bit further.
