Wave lapping calmly on the beach
Pebbles worn smooth along the coast
The beauty of windswept sand dunes

These are some of the images that inspired this cozy cardigan design. When planning for this pattern began, I knew I wanted to use brioche for a couple of reasons. First, the plump texture traps warmth close to the body for a fabric that will keep you warm all day long. Second, I love the way brioche fabric can be textural and graphic at the same time. The wave motif worked sideways along the hem and echoed down each sleeve was a fun challenge to design, and I wanted a graphic element that captured the beauty of a windswept coastline. This is a sweater that is fun to knit and will keep you warm and cozy all winter long.

The Brith cardigan is an open-front raglan brioche cardigan worked seamlessly from the top down. After casting-on around the back of the neck, raglan increases are worked simultaneously with v-neck increases to shape the yoke and v-neck opening of the sweater. The body includes optional A-line shaping and a wave hem that is worked sideways starting from the center back around to the front on either side. The sleeves are worked without sleeve decreases for a slightly gathered look around the cuff and finished with a tubular bind-off. Once the body is complete, stitches are picked up along the front and neck opening to knit a generous shawl collar, which is finished with an i-cord bind-off. Finally, the hem is also finished with an applied i-cord.

Disclaimer: in an attempt to be size inclusive, I have graded the pattern for people with a bust measurement up to 64in/162cm (potentially larger if worn with less than the suggested positive ease). However, I could not find people to test some of the larger sizes, so sizes 7-9 have not been test knit. If you are interested in testing one of these sizes for me, feel free to get in touch, and I would be happy to discuss testing details with you, including a free copy of the pattern.

Love it!

Amazing design, and the inside is almost as pretty as the outside. I never knit a full garment in brioche before this, but there were enough explanations and tips that I managed a perfect fit. Well worth knitting.
