This tutorial explains an increase method that involves working multiple stitches in a single stitch. A (k1, yo, k1, yo, k1) all in the same stitch is a quadruple increase, working 5 stitches in one stitch, it increases 4 stitches. You may find this type of stitch in lace knitting. Let’s see how it works.

What IS a (k1, yo, k1, yo, k1) increase anyways?

This is a quadruple increase, meaning you are increasing 4 stitches. To increase 4 stitches from just 1 stitch you’re going to work multiple stitches without taking the stitch off the left hand needle. So you’ll knit the stitch (without taking it off the left hand needle), then work a yarn over, then knit that same stitch again (without taking it off the left hand needle), another yarn over, and finally a regular knit stitch where you take the stitch off the left hand needle. You’ll have used 1 stitch to create 5 stitches, for a gain of 4 stitches.
If working a yarn over is new to you check out our yarn over (yo) tutorial here.

How to work a (k1, yo, k1, yo, k1) all in the same stitch
- Knit the first stitch on the left needle without taking it off.
- Work a yarn over (yo).
- Knit the stitch on the left needle again, without taking it off the needle.
- Work another yarn over (yo).
- Work a regular knit stitch, taking the stitch off the left needle.





How does this increase look in an increase line?
As the increases start to stack up you can see how the increase line looks. You can see that the stitch with 5 stitches worked into it tends to stretch a bit, creating a decorative hole.
For this swatch I’ve worked a (k1, yo, k1, yo, k1) all in the same stitch every 4th row.

An unusual and very pretty increase.
