How to Work the 2 Row Mosaic Crochet Technique

The technique for mosaic crochet may look quite complicated and fiddly but I promise it isn’t once you get the hang of it!

Mosaic crochet in general, but especially the 2 row crochet technique, has become really popular in the last few years. You can create some amazing geometric and fun designs with it.

It looks similar to interlocking crochet but the technique is quite different.

In this version you work two rows of crochet in one colour leaving spaces wherever stated in the mosaic chart or pattern and then work a further two rows in another colour.

This second colour allows you to ‘fill in’ the spaces you left to create the design whilst then also leaving new spaces for subsequent rows.

Like anything craft related, it sounds complicated but in practise is simple so I’m really excited to show you how I do it!

How to read a mosaic crochet chart

I think the easiest way to work a mosaic crochet technique is by reading the chart rather than the word pattern but I provide a worded version in my patterns just in case people prefer that instead.

In this tutorial I’ll be showing you how to read the mosaic chart.

A mosaic chart generally looks something like this: (this is my Wanderers Mosaic Crochet Blanket Pattern if you’d like to make it!)

mosaic crochet chart

The chart is read from the bottom to the top with each row representing 2 rows of the same colour of crochet.

The first pass Row 1,2,3 etc (RS: right side) is read from right to left, the second pass Row 1a, 2a, 3a etc (WS: wrong side) is read from left to right.

Each square on the chart represents a st or skipped stitch.

The colour you are working with are the stitches for that row, any other colour are the skipped stitches and you need to work a ch1 (or more traditionally a ch2) and skip the stitch.

For a RS row any st into a dc (US sc) of previous row is a dc (US sc), any st into a skipped st 3 rows below is a tr (US dc).

If you would like to learn another way of doing it then read about the one row/round mosaic crochet, back loop only technique instead which you can use in rows (with lots of ends) or rounds.

2 Row Mosaic Crochet Technique

The following tutorial photos are just a guide to show you how the technique works and are not following the above chart directly.

Once you find the mosaic crochet pattern you’d like to make then you can just apply these principles to it.

Also – you can make your own charts! Once you’ve mastered the mosaic crochet technique the sky is the limit and with a bit of planning and thought you can make whatever you like.

Special Stitches

The mosaic UK treble/US double crochet is worked in front of chain stitches on the 2 rows below, into skipped stitches of the same colour three rows below.

As an example, here’s what a worded version of a mosaic crochet pattern might look like: the term st stands for either a mosaic UK treble/US double crochet stitch or a UK double/US single crochet as required.

Row 2: ch1, st in 4, *(ch1, skip st, st) 6 times, st in 4, (ch1, skip st, st) 6 times, st in 6, rep from * once more, (ch1, skip st, st) 6 times, st in 4, (ch1, skip st, st) 6 times, st in 3.

Row 2a: Rep Row 2, change colour.

Row 3: ch1, st in 3, *ch1, skip st, st in 11, (ch1, skip st, st) twice, ch1, skip st, st in 11, ch1, skip st, st in 5, rep from * once more, ch1, skip st, st in 11, (ch1, skip st, st) twice, ch1, skip st, st in 11, ch1, skip st, st in 3.

Row 3a:Rep Row 3, change colour.

2 row mosaic crochet technique step 1

Step 1

Mosaic crochet begins like any other pattern with a foundation chain.

2 row mosaic crochet technique step 2

Step 2

Beginning in the second chain from the hook work a row of UK double crochet or US single crochet stitches.

This is Row 1 reading from right to left on the chart. Then follows a repeat of the row – this is Row 1a reading from left to right on the chart. Each row on the chart represents 2 rows of actual crochet.

Each square on the chart represents a stitch or skipped stitch. The colour you are working with are the stitches for that row, any other colour are the skipped stitches and you need to work a ch2 and skip the stitch. (You can work a ch1 if you keep your tension relaxed).

For any RS row any st into a dc (US sc) of previous row is a dc (US sc), any st into a skipped st 3 rows below is a tr (US dc).

Step 3

You now need to work Row 2 by following the rules above, work a dc (US sc) for any square that is the colour you are working in, work a chain space (you can work a ch2 or ch1) for any square that is a different colour.

Step 4

Row 2a is going to be a repeat of Row 2 reading the chart from left to right.

Step 5

Change colour at the end of the row before turning.

2 row mosaic crochet technique step 6

Step 6

Row 3 is now worked in the new colour, reading the chart from right to left. Again, each square in this new colour is either a dc (US sc) or tr (US dc) and any square in a different colour is a chain space and skip the stitch.

Step 7

To work a mosaic UK treble/US double crochet into a skipped stitch 3 rows below insert the hook into the unworked stitch – note how the hook is not through to the back of the work but rather hooked around the stitch so that your stitch will be sitting at the front of your work only.

Step 8

Yarn over the hook and pull through two loops. Yarn over and pull through two loops again to complete stitch.

Chart Example

As you see here – Row 3 shows where you need to work the darker colour into the stitches into Row 1 below. (Which will actually be 3 rows of crochet below).

2 row mosaic crochet technique step 9

Step 9

Continue along the row working either a dc (US sc) or tr (US dc) as indicated and any square in a different colour is a chain space and skip the stitch according to the chart or pattern.

2 row mosaic crochet technique step 10

Step 10

Row 3a is a repeat of Row 3 reading the chart from left to right. Work a UK dc/US sc into any stitch worked on the previous row, regardless of what that stitch is. Work a chain space in the same places as the chain spaces on the previous row.
