What is an Invisible Decrease?

An invisible decrease is a crochet technique that joins two stitches together using only the front loops, creating a smooth and seamless finish

Unlike standard decreases, it:

  • Prevents holes
  • Reduces bulk
  • Blends into the fabric

How to Crochet an Invisible Decrease (Quick Steps)

  1. Insert hook under front loop of next stitch
  2. Insert hook under front loop of following stitch
  3. Yarn over
  4. Pull through first two loops
  5. Yarn over, pull through remaining loops

 That's one invisible decrease complete.

Step-by-Step Instructions

Step 1

Invisible Decrease vs SC2TOG

This is one of the most important distinctions:

Invisible Decrease:

  • Uses front loops only
  • Smooth, seamless finish
  • Ideal for amigurumi

SC2TOG stitch:

  • Uses both loops
  • Creates a visible bump
  • Standard decrease method

Invisible decrease is essentially a refined version of sc2tog.

When to Use an Invisible Decrease

Use invisible decrease when you want:

  • Smooth shaping
  • Professional-looking finishes
  • Tight fabric with no gaps
  • Clean amigurumi results

It's widely used in stuffed toys to avoid holes showing stuffing.

Try these patterns:

  • Crochet mini octopus pattern (a quick crochet project)
  • Sitting crochet angle pattern (invisible decrease is used to shape the head and neck in the amigurumi pattern)

Common Mistakes (and Fixes)

  • Using both loops instead of front loops - This turns it into a regular decrease
  • Pulling loops too tight - Causes distortion in stitches
  • Working on wrong side of fabric - Decreases won't look "invisible"
  • Incorrect hook placement - Always go through front loops only

Beginner Tips

  • Use stitch markers to track decreases
  • Practice slowly to build muscle memory
  • Use lighter yarn to see loops clearly
  • Keep tension consistent

Stitch Anatomy Tip

Understanding loops is essential for this stitch.
