Joining and seaming Cable & Crossed Cardigan

Once you’ve stitched all the pieces (and blocked to size) it’s finally time to sew them all together and finish your project, ready to wear!

Joining & Seaming | Cable & Crossed Crochet Cardigan

There are a number of ways you can choose to sew your project together, but the sewing technique recommended to create the least bulky seam would be to use the mattress stitch.

There are 3 commonly used techniques to block your crochet projects, and the one to use will depend on the fibre in the yarn you have used. Click here to find out more about each technique and which is the best to use on your project.

I used 100% acrylic yarn so chose to steam block each part of the cardigan to ensure I achieved the correct finished size – it also improved the finished look to my stitches greatly.


The Cable & Crossed Cardigan pattern will be releasing as a crochet along, with a different section of the pattern releasing each week.

There is never any pressure to keep up with the releasing of the pattern sections – but it can be fun to try! Below you will find a list of when the pattern elements will release.

Each pattern section will have it’s own video tutorial to help you complete your cardigan with absolute confidence.

What size are you making?

Before you begin to join and seam your project, it is highly recommended to block each section to the size recommended in the schematic. I’ve shared it below for you to check the sizes of your finished panels and sleeves.
