An Intermediate Cardigan Knitting Pattern

This cardigan knitting pattern is an intermediate level for anyone who is an experienced knitter.

Knit in the Irish moss stitch pattern, the cardigan has shaping through increases, decreases, and short rows.

Each piece is worked from the lower band up, and the front bands and collar are picked up and knit later.

The Yarn I Used

I made the cardigan using a bulky/chunky/12 ply yarn – The Petite Wool from We Are Knitters.

This meant the sweater was knit up on size 5.5 mm (US 9 ) and 6.5 mm (US 10.5 ) knitting needles.

I selected the color olive, but this cardigan could be made in any color you like.

You could substitute this yarn with any yarn that is bulky/chunky/12 ply yarn like Paintbox Yarns Simply Chunky from Love Crafts.

Irish Moss Stitch Knitting Pattern

The Irish Moss Stitch is a textured knitting pattern that creates a fabric with small, tightly packed bumps.

It alternates between knit and purl stitches both horizontally (row to row) and vertically (stitch to stitch), giving the finished piece a bumpy, all-over texture.

Basic Irish Moss Stitch Pattern

The Irish Moss Stitch is typically worked over an even number of stitches, using a 4-row repeat knit stitch pattern:

Row 1: *P1, K1* rep to the end of the row.
Row 2: *P1, K1* rep to the end of the row.
Row 3: *K1, P1* rep to the end of the row.
Row 4: *K1, P1* rep to the end of the row.

Key Features:

Texture: The alternating knit and purl stitches create a richly textured, bumpy surface.
Reversibility: This stitch is a reversible pattern, meaning both sides of the fabric will have the same appearance, making it ideal for scarves, blankets, and other items where both sides are visible.
Uses: The Irish Moss Stitch is often used for sweaters, blankets, scarves, and other knitwear to add texture and structure to the fabric.

This stitch is similar to the seed stitch, but while seed stitch changes the stitch pattern with every row, Irish Moss changes every four rows, creating a more compact texture.

It is also similar to the double moss stitch pattern or double seed stitch, which is a textured knitting stitch pattern that creates a fabric with a raised, bumpy surface.

This intermediate pattern is great for any experienced knitters.
