Supplies and Materials

These are the supplies and materials you need to be able to crochet this sweater:

  • DROPS Cotton Light, color 14 (dark turquoise): 1166, (1265, 1387, 1586, 1722, 1829, 2004, 2187) yds
  • 5mm / H-8 crochet hook (I use these hooks)
  • 6mm / J-10 crochet hook (foundation chain and row 1)
  • Stitch markers (these are my favourites)
  • Scissors
  • Yarn Needle

Yarn Choices

DROPS Cotton Light is a DK yarn I bought in a sale earlier this year from Wool Warehouse. It’s been in the back of my mind so when I’d chosen the stitch and designed the style for this sweater pattern, I knew it would be just right!   I’m so pleased with the finished weight of the garment and love the drape.

BrandDROPS Cotton Light
Yarn WeightDK
Fibre Blend50% Polyester 50% Cotton
Length105 metres / 115 yds
Ball Weight50g
Care InstructionsMachine wash 40°C Dry flat Do not tumble dry

I do recommend you use DK and if possible, a similar blended yarn to achieve the same drape.  However, you can substitute the Cotton Light and adjust your stitch count using the stitch gauge converter tool.

Note: I’ve used a larger hook than recommended with the yarn to open up the lacy stitches.

How the sweater pattern is worked

The Lottie sweater uses the ascending shells stitch pattern throughout the body and sleeves.  This is made up of double crochet, V-stitches and chains and is worked in a 4-row repeat.  The open stitches give a gorgeous lacy fabric and drape!

An easy construction, you’ll crochet two rectangular panels first (for front and back).  There is no shaping for these panels.

The sleeves are crocheted next and use minimal decreases for shaping.  Decreases are made working stitches together and single crochet in chain spaces.

Next, you’ll start to assemble the sweater starting with the shoulder seams.  The front and back are placed together with the wrong side facing outwards.  Stitch markers are used for the middle of the neckline and where the seam starts on right and left.

Once you’ve done this, the sleeves are set in place and seams are sewn for the sleeve and side seams. 

The sleeves are set in place by lining up the shoulder edge of the sleeve with the shoulder edge of the right and left fronts, pinning into place and sewing along the shoulder edge. 

The sleeve is then folded in half and you can either sew the seam from the cuff and continue the side seam (recommended) or if you prefer, you can sew from the body to the cuff then the side seam separately. 

Sewing one seam to close the sleeves and the side of the sweater with one length of yarn is better as it gives a stronger seam.  However, if you don’t like working with a longer length of yarn (that can get easily tangled) you can work the seams separately.

The image below shows how to lay out your lacy top ready for setting the sleeve in place and folding the sleeve.

And that’s it!  Your lacy summer sweater is ready to be blocked and worn.
