How to Invisible Increase in Crochet


Updated on by

If you've been crocheting amigurumi for a while, you've probably heard of invisible decrease. But did you know there's such a thing as an invisible increase too?

While increases are usually less noticeable than decrease, traditional increases can still create visible gaps, especially when you're wokring with tight stitches or using a contrasting color. Invisible increase is a simple trick that gives your work a cleaner, more polished look, especially important for projects like stuffed animals, dolls, or anything worked in the round.

What is an Invisible Increase?

A standard single crochet increase usually involves making two single crochet (sc) stitches into the same stitch. While that's totally fine, it can stretch the stitch and leavea. bit of a gap.

The invisible increase technique still works two crochet stitches into the same stitch, but we change it up by working one of them in the back loop before working the second stitch in both of the loops.

This technique would also work if you choose to work the first crochet stitch in the back loop and then work the second stitch into both of the loops.

This helps distribute the stitches by putting one in front of the other, making it look more like one stitch.

This method will come in handy when you want the increase to be less visible. However, it will appear different on the wrong side of the fabric as compared to the traditional increase.

When to Use an Invisible Increase

Use this technique any time you want a smoother, less noticeable shaping in your crochet, especially in:

  • Amigurumi heads and bodies
  • Stuffed limbs
  • Spherical shapes or toys with curved surfaces

It's not always necessary, but it adds a subtle level of refinement that makes your work look extra tidy, especially when you're photographing it for a blog or listing it for sale!

Bonus Tip

  • Keep your tension even: Invisible increases look best when your stitches are consistent in size.
  • Use a stitch marker: Especially helpful when you're working in spirals and don't want to lose track of where the increase happened. Learn how to use a running stitch marker.
  • Pair it with the invisible decrease: Using both techniques will give your amigurumi a smooth, seamless finish from top to bottom.
