Oftentimes mosaic crochet is read from a chart rather than written instructions and this can be super intimidating at first! If it’s the mosaic crochet charts that have you running for the hills, then check out this blogpost all about how to read a mosaic crochet chart.

Overlay Mosaic Crochet Technique

We are using overlay mosaic crochet worked in rows for the cardigan, so that means that you only use 1 colour of yarn per row, which you fasten off at the end of each row.

The body is then worked in long rows down the cardigan using the join as you go technique.

For overlay mosaic crochet, we need US single crochet (UK double crochet) and US mosaic double crochet (UK mosaic treble crochet) stitches to create the patterns.

 We change colour every row of the yoke and we work either a single crochet into the back loop only of the stitch, or we work a mosaic double crochet stitch into the front loop of the stitch 2 rows below. This is all explained in much more detail in our mosaic crochet tutorial.

Fancy trying out the technique on a smaller project first?

Mosaic Crochet Charts

The other important aspect of this technique is learning how to read a mosaic crochet chart. Again, they aren’t as complicated as they look and you’ll pick it up in no time!

Another thing to know though is that you don’t have to read the charts to make the pattern! Each row is written out in full if you prefer to follow that way 🙂

Making Your Mosaic Crochet Cardigan Perfect For You

Although the garment comes in so many sizes, there are still some things you can easily do to adjust it to fit you perfectly. I suggest choosing the garment chest size that you’d feel most comfortable wearing and then checking ‘customisation’ below for details of how you can adjust various parts.

Once you have chosen the correct chest size you’d like to make, the rest of the design is easy to adjust to fit as you would like it to.

The Cardigan is designed to have a small amount of ease all over with straight sleeves. The garment is worked from the top down so it is simple to change the length of both the Body and the Sleeves as you’d like.

If you like this cardigan pattern, you might also like the other mosaic crochet sweaters I have created too:

BODY FIT

Proportion of Back and Front Stitches

The pattern is written to have have equal space at the Front and Back to allow for the Button Band. However if you would like to change this you can.

If you would like more room at the Front then you can work less stitches for the Back and more for the Front as desired. Every 10 sts will adjust by 2 inches. The great thing about the top down construction means you can try this on and adjust to suit you perfectly.

Sleeve Armhole Depth: You can adjust the armhole by working more or less Back Short rows. Each row will add another stitch to the armhole and you can continue to adjust until you have the perfect fit.

Before adjusting the armhole I would recommend blocking the Yoke to see how that changes the overall fit.

Are crochet cardigans your thing? I love them too! If so, I have plenty more ideas for you that use loads of different styles and techniques you’ll love:

LENGTH

Main Body Length: To adjust the length, you can work more or less chains for the Body as you like. If you don’t want a Bottom rib then work just the Body stitches for your chain and not the Cuff Stitches.

Bottom Rib: you can adjust the Bottom Rib length by working more or less chains to start this section.

Sleeve Length: You can adjust the Sleeves by working as many or as few rounds of the Sleeves before adding the Sleeve Cuff if desired. If you don’t want a Sleeve Cuff then work the Sleeves to the final length you desire and fasten off.

Make sure to work a matching number of rounds for each sleeve.

Check out the matching mosaic crochet sweater pattern for more options for the body and sleeves.

Pattern Gauge

Gauge: 20 sts and 18 rows over sc in blo = 4″ x 4″ / 10cm by 10cm

Making a crochet gauge swatch is important when crocheting projects like garments to ensure that it ends up the desired size.

If you’d like to work a swatch ahead of purchasing the pattern then you can do this as follows:

Row 1: Using the larger hook, Fsc25, break yarn. [25]

Row 2: with RS facing, join yarn to first st of previous row, ch1, sc in blo of each st, break yarn.

Repeat Row 2 until you until you have enough to measure and be sure your gauge is correct.
