Centred Double Increase Step by Step

Centered Double Increase Step by Step

Some time ago, I made a tutorial about a double vertical decrease, and I’ve got a comment with a question about the best way to make a double increase that matches the look of the double vertical decrease.

After doing some research and quite a bit of swatching, I found out that we get the best match when we use paired increases explained by Elizabeth Zimmermann in her book “Knitting Without Tears”.

This method is very simple, and it creates neat increases that do not form holes and do not cram the fabric.

When we place these increases at the sides of one stitch, we get a lovely chain of stitches at the centre of the increase just like a chain of stitches formed at the centre of the double vertical decrease.

Here’s how this neat double increase works step by step (watch the video below or download a Quick Reference Card from the Library of Free Knitting Resources).

This increase is made in exactly the same way both when we work flat and when we work in the round.

Remember to purl the central stitch in the wrong-side row (or knit it in the next round, if you work in the round) to keep the chain of stitches uninterrupted.


The full step-by-step photo tutorial about this method, is a part of the Knitting Collection #3. Once you order your copy of this collection, you will instantly receive a “big PDF” (315 pages!) with this and 50 other tutorials included in the collection.

You will also receive one e-book and six knitting patterns as a special bonus, so go ahead and get it all right now before you forget 😊

  1. Maryna,
    I have learned so much through all of your tutorials! Thank you for that. I am wondering if you could use the Centered Double Increase instead of a garter tab when knitting a triangular shawl.
