This breezy, lightweight cardigan is perfect for summer! It’s an easy, beginner-friendly project you can make today, from just two crocheted rectangles.
As I’ve said before, I love summer crochet projects. It’s pretty hot here in Florida, and it stays that way for most of the year. So I am always excited to try a new summer garment project.
This one is definitely a winner!
Even though I used a #4 Worsted Weight yarn, this cardigan is worked at a loose gauge, making it breathable and lightweight. You get the best of both worlds – a breezy, lightweight fabric, with the speed of a worsted weight yarn. The flowy, over-sized style looks great on every body type. And best of all, it’s made from just two rectangles! If you’ve never crocheted a garment before, this is the perfect place to start!

You Will Need:
Approx. 450 (600, 750) yards of #4 Worsted Weight Yarn (I used Red Heart Super Saver Ombre, 1 (2, 2) skeins)
US Size L (8.0 mm) Crochet Hook
Yarn Needle or Blunt Tapestry Needle
Gauge: 10 stitches = 4” (10 cm), 4 rows = 3” (7.6 cm) in double crochet
dc: double crochet
*Fdc: foundation double crochet
*CSDC: chainless starting double crochet
*This is a special stitch. See instructions below to learn how to work this stitch.
Foundation Double Crochet: (video tutorial here)
To begin, chain 2. Yarn over, insert hook into the 2nd chain from the hook. Yarn over, pull up a loop. Yarn over, pull through one loop on hook. Yarn over, pull through 2 loops on hook. Yarn over, pull through 2 remaining loops on hook.
For all following stitches: Turn work upside-down so the bottom (foundation) edge is facing you. On the bottom of the previous stitch, there is what looks like the top of a normal crochet stitch. Yarn over and insert hook into both strands of that “stitch”. Yarn over, pull up a loop. Yarn over, pull through one loop on hook. Yarn over, pull through 2 loops on hook. Yarn over, pull through 2 remaining loops on hook.
Chainless Starting Double Crochet: (video tutorial here)
Stretch loop on hook until it is slightly longer than a regular double crochet. Holding the top of the loop still with your finger, yarn over with the stretched loop on your hook (not the working yarn) 1 time. Insert the hook into the same stitch the loop is coming from. Yarn over, pull up a loop of yarn. *Yarn over, pull through 2 loops on hook* 2 times.
Side Panel (make 2):
Row 1: ch 2. Sk 1st ch, work a fdc in 2nd ch from hook. Work 114 (120, 124) more fdc. You should have 115 (121, 125) sts, not including beg chs.
Row 2-3: Turn. CSDC in same st. Dc in ea st across. You should have 115 (121, 125) sts.
Row 4: Turn. CSDC in same st. *ch 1, sk 1, dc in nxt st* across. You should have 115 (121, 125) sts.
Row 5: Turn. CSDC in same st. Dc in ea st and in ea ch sp across. You should have 115 (121, 125) sts.
Repeat Rows 2-5; 2 (3, 4) more times. Then, repeat Rows 2-3 once more. You should have a total of 15 (19, 23) rows. Tie off, leaving a tail about 1 yard / 1 m long.
Note: Leave a tail about 1 yard / 1 m long before beginning the 2nd panel. This yarn tail will be used to sew the center back seam.
To Block: (video tutorial here)
For natural fibers, pin project out to the correct measurements on foam blocking mats. Spray with water until fully saturated, allow to dry.
For acrylic fibers, pin project out to the correct measurements on an ironing board or several layers of towels. Hold a steaming iron 2”-3” over the surface of the fabric, making sure all of the fabric is penetrated by the steam. Allow to cool / dry.
After blocking, each panel should measure:
Size 1: 11 ¼” by 46” or 29 cm by 117 cm
Size 2: 14 ¼” by 48” or 36 cm by 122 cm
Size 3: 17 ¼” by 50” or 44 cm by 127 cm
First, we will sew the center back seam. Lay panels out flat so the long foundation edges are touching. Thread the long tail from the foundation edge of one panel through your yarn needle. We are going to whip stitch the foundation edges together, and stop close to the halfway-mark. Each time we take a stitch with the yarn needle, we will be inserting into one stitch from the foundation edge of each panel, joining one pair of stitches.
Take your yarn needle and whip stitch 50 (53, 55) pairs of stitches together. Insert your needle again through the same pair of stitches you just went through, wrap the yarn around the needle, and pull the needle through to make a knot. Weave in the yarn tail.
Now we will join the side seams. At this point, the panels are partially seamed together down the middle. The seamed section is the back of the cardigan, and the sections that are not seamed together yet are the front sections of the cardigan.
Bring each front section down so the short edge of the front section meets the short edge of the back section. At the top, the folded edges of the front panels make the shoulder portions of the cardigan.
Beginning at the bottom corner, line up the side edge of the front with the side edge of the back. We will be stitching the side edges together, leaving an opening at the top for the armhole.
Thread the long yarn tail from one of the corners through your yarn needle. Beginning at the bottom corner, we are going to whip stitch the side edges together, and stop about 2/3 of the way up. Each time we take a stitch with the yarn needle, we will be inserting into one stitch from the edge of each panel, joining one pair of stitches.
Take your yarn needle and whip stitch 34 (36, 38) pairs of stitches together.
Insert your needle again through the same pair of stitches you just went through, wrap the yarn around the needle, and pull the needle through to make a knot. Weave in the yarn tail.
Repeat for the other side seam.
