CROCHET SWEATER PATTERN DESIGN PROCESS

My Shoreline Sweater pattern is an easy crochet garment make. I designed this crochet sweater pattern in nine different sizes because everybody should make one!

I wanted to design a beginner friendly crochet sweater pattern for a while now. Sometimes it doesn’t hurt to keep things nice and simple.

I have been inspired by the french riviera and shoreline of southern France. My aim was to capture this feeling in a crochet sweater that you can wear all year round.

I think the colour combination of navy and white is so classic and timeless. Paired up with a softer pink colour it creates the perfect pullover to wear with jeans or white shorts.

CHOOSING THE PERFECT YARN FOR YOUR CROCHET SWEATER PATTERN

I have chosen to use Cygnet Yarns DK for my crochet sweater pattern. This yarn is on the thinner side of DK weight yarns which worked perfectly for this crochet sweater.

It makes it a lightweight and breezy crochet sweater that can be worn for most of the year. Here in UK especially.

I really loved the vibrant colours of Indigo blue and White which is such a gorgeous colour combination. For my third colour I have chosen Flash which is a lovely soft shade of pink.

You could use a few different colours for the top part. Lime green, yellow, apricot even mustard yellow would look stunning.

This sweater would be a great stashbusting project too because you could go all out and use different colours!

CROCHET STITCHES

For my Crochet Shoreline Sweater I have used herringbone double crochet stitch (HBDC). I have totally fallen in love with this crochet stitch! It is so easy to memorise.

Because by changing just one loop to pull the yarn through you get a totally new interesting looking stitch!

I have made a quick herringbone double crochet video tutorial. In this video I show you how to increase on the sleeve rows.

I also share me favourite way to join yarn into your project securely.

While you wait for yarn delivery, pin this for later!

CROCHET SWEATER PATTERN NOTES

The sweater is constructed from front and back panels and 2 sleeves worked separately which are sewn together at the end.

The back panel is worked as a straight rectangle piece. The front panel has a lowered neckline at the front by splitting the last 4 rows and leaving stitches out in the middle to accommodate for the neck collar.

The sleeves are worked bottom up from cuffs increasing at either end of the sleeve rows every 3-4 rows depending on the size you are making.

I have made a video tutorial for the sleeve increases you can watch here.

CROCHET SWEATER PATTERN SIZE ADJUSTEMENTS

  • the number of rows on the bottom hem determine the width of the jumper. To adjust the width, add/take away any number of rows from the bottom hem. Remember to do so on both the front and back panel
  • the number of rows determines the length of the jumper. To adjust the length, add/take away number of rows on the body. I’d suggest adjusting the number of rows in Flash/yarn C to keep the 4 row repeats in yarn A and B. Unless you are adding or taking away multiples of 4 rows.
  • For a wider/narrower neckline, take away/add number of stitches to the shoulder part of the front in Neck Shaping. Remember to do so on both sides to keep the neckline even.
  • The width of the sleeve is determined by the number of rows of the bottom sleeve cuff. To adjust the overall width of the sleeve, add/take away number of rows of the sleeve cuff.
  • The sleeves are tapered by working increase row every 4th row for sizes XS-L and every 3rd row for XL-5XL. You can taper the sleeves more/less by working an increase row less/more often.
  • The last row of the sleeve is worked in Flash (yarn C) to unify the colour for joining, the join is less visible if seaming 2 pieces in same colour.
