Mosaic Knitting and Tutorial: Slipping Stitches

If you’ve never tried mosaic knitting, let us tell you something about it: IT’S SO FUN! It’s a way to create a colorwork pattern while only holding one yarn at a time, just knitting/purling and slipping stitches. Really, that’s it. All these beautiful designs were created with mosaic knitting (these are all from our collection Mosaic Medley).

It’s also possible to use mosaic in combination with other techniques, like cables (as in the hat above), but usually it really is just knits and slips, and sometimes purls. Another new design that uses this technique is this month’s A Year of Hats pattern, Links (in worsted and fingering weights):

It might feel overly formal to call mosaic knitting a “technique” because it really is just using slipped stitches along with more than one yarn color. So there’s not really anything special to learn—if you can knit/purl and follow a chart, you can just jump right in! But let’s break it down. First, let’s talk about slipped stitches.

Slipping a stitch means passing it from one needle onto the other needle without working it (usually from the left-hand needle to the right-hand needle, unless you knit left-handed, then flip it). “Working” the stitch means knitting or purling it; so when slipping a stitch, you won’t knit or purl it, just move it across onto the working needle.

right-hand needle is inserted into stitch on left-hand needle, purl-wise. Image description: a close-up view of hands knitting a mosaic swatch made of medium blue and white stitches.

Unless a pattern says otherwise, all slipped stitches are worked purl-wise, as you see above. Insert the needle into the stitch as if you were going to purl. This means the stitch is not being twisted as it passes from one needle to the other. See below how the position of the stitch stays the same, with the front leg going to the right:

Also, unless the pattern notes otherwise, the yarn will always be held to the wrong side of the knitting when slipping a stitch. So, when you are working a right side row (or round), the yarn is held to the back; if you are working a wrong side row, the yarn is held to the front. This way the yarn is always going across the back side of the knitting, just like in stranded colorwork.

Here is a little animation of that slip being worked:

And here is that same slip in the context of the stitches around it; in this case, you’ll see 2 stitches knit, then 1 stitch slipped, then the fourth stitch knit:

This is how mosaic patterns work: switching back and forth between knits (or sometimes purls) and slips to create the colorwork pattern, with the stitches meant to be in the held yarn color worked, and the stitches meant to be in the other color slipped. So a mosaic chart will look something like this:

Mosaic charts look similar to colorwork charts featuring two (or sometimes more) colors in each row. In mosaic knitting, you’re knitting with one color only and slipping the stitches of the second color not being used to knit that row. Most commonly, as in this pattern, you’ll be working two rows (or rounds) in one color, followed by two rows of the other color, throughout. In this chart, the numbers on the right are colored with the yarn being held on that row.

Usually, mosaic patterns will be charted, not written out, because they are so visual (similar to stranded colorwork patterns). There could be other symbols in a chart (like decreases for the crown) but usually knit/purl/slip stitches will be the main three types of stitches, often only knits and slips.

Something worth noting: mosaic patterns will usually have you slipping the same stitch for more than one row. This is fine! Many mosaic patterns (like the Links hat) repeat the same row twice to create the pattern, as you can see in the chart excerpt above. Each slipped stitch will always be slipped for two rounds before being worked again. Since this is also happening to the other stitches around it, this all evens out and lays flat (if you were doing a column of mosaic knitting, surrounded by plain stockinette stitch, this wouldn’t be so simple).

Because of the slips, the row gauge of mosaic patterns will be much denser than standard knitting; when knitting mosaic, you are basically knitting twice as many rows as you are actually creating. If one stitch is knit on one row, then slipped on the following row, two rows have been worked, but only one row has actually been created on that stitch. Make sense? If you’re following a pattern, but if you’re wondering why it seems like this project is taking longer than it should—that’s why!

Mosaic is so much fun to knit, and the rhythm of the slip/knit makes the rows speed by! We hope you’ll give it a try and you’ll be hooked, just like we are. Let us know if you have any questions, of course, and happy mosaic knitting!

    Another typically inspiring, informative and really pretty post from my friends at KP. This is the first time that I’ve read a blog post about mosaic knitting and wanted to cast something on right away! Thank you! My bookmark collection from this blog is growing!

    Yes, I have done several pair of socks in mosaic and I do love it. Your blog is very inspirational so I will have to try it now on some different pieces.

    Beautiful! I am almost brave enough to try. Love the blanket in top pic. Thank you.

    I did not know what mosaic knitting was but now I feel inspired to try it out. The technique is so simple, yet the effects are so intricate!
