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!

A quick and easy summer cardigan crochet pattern, perfect for beginners.

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

Scissors

Measuring Tape

Yarn Needle or Blunt Tapestry Needle

Gauge: 10 stitches = 4” (10 cm), 4 rows = 3” (7.6 cm) in double crochet

Abbreviations:

beg: beginning

ea: each

nxt: next

st: stitch

sts: stitches

sp: space

sk: skip

ch: chain

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.

Special Stitches:

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.

Made from two rectangles, this lightweight cardigan is lightweight and breathable, with the speed of being worked in worsted weight yarn.

Seafoam Cardigan Instructions

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.

OR

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

Quick and easy summer kimono cardigan crocheted in ombre yarn

Assembly:

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.

Enjoy your finished Seafoam Cardigan!

    I would like to make size 2 longer. Approximately
    midcalf… how many chains would I need?

    Thanking you in advance!

      Hi Connie. If you’d like to make it longer, here’s how you can do that. First, measure down from the shoulder to see how long you want the finished cardigan to fall. Then, work your foundation edge so that it is twice as long as you want the finished cardigan to be, making sure you have an odd number of stitches. (It needs to be twice as long as the finished length, because half of the piece will be part of the front and the other half will be part of the back.) You can then follow the remaining pattern instructions as written. I hope this helps!

    I would like to make this longer. I’m doing size 2. If I add 10 stitches to the beginning then I should end up with a finished length of 28″ (shoulder to bottom). Does that sound right?

    Reply
    • Yay for Yarn

      Hi Nancy! Because the rectangle will be one half of the cardigan, creating both the front and back of one side, adding 10 stitches will add 2″ to the front and 2″ to the back. If you’d like to add 4 inches to the finished length, you’ll need to add 20 stitches to the foundation row. This will add 4″ to the front and 4″ to the back. I hope this helps!

    Hello I have a question. when you crochet in three pieces. how do you get the front & back panel yarn color to match? It looks like it’s crocheted in on piece?

    Reply
    • Yay for Yarn

      Hi Margaret. With the two-piece construction, if you want the ombre colors to blend in, here’s what you can do. After you’ve finished the first panel, if the yarn coming from the skein is not the same color as the foundation edge of the first panel, keep pulling yarn out of the skein until you reach the color that matches the foundation edge, and start your second panel with that color. If you want to make sure that the colors match with the ombre yarn, you may want to make sure you have a bit more yarn than the pattern calls for. I hope this helps!

    Hello! I’m working on this cardigan with Red Heart Super Saver. I like your design and hope you design more like these. Just wondering, is it possible to tweak the sewing portion of the cardigan? Thanks!

      Hi. Yes, you can tweak the seams, as far as sewing them together further up or stopping before the instructions tell you to. I hope this helps!

    Hi, I really love your pattern! Do you think I could transform this lovely cardigan into a summer top by sewing the front pieces together as well? Should I make the two panels bigger?
    I am about to start making it and I would much appreciate your reply!

      Hi Elizabeth! Yes, you could make this into a top by sewing the front panels together. You wouldn’t need to alter the panel size, just make another seam up the front to close the front of the cardigan. I hope this helps!

    Hi! Sorry to bother you again. As I said before, I’m currently working on your cardigan. I love the pattern and it looks beautiful so far. Before I assemble it, is it really necessary to (steam) block the panels? I only have a normal clothing iron and I’m only 12 so I’m afraid it might be complicated. Do you have any other recommendations or other ways to block that may involve moisture or water, but not a steam iron? Thank you so much, I appreciate it.

    Reply
    • Yay for Yarn

      Hi Clementine! If you would rather not steam block your pieces, you could wet block them instead. To do this, you’ll get the pieces wet, gently squeeze out the excess water, and lay them out flat on a couple layers of towels to dry. However, if your yarn is acrylic and / or machine washable, you can just throw the pieces into the washing machine, gently squeeze the excess water out, and lay them flat on towels to dry. The idea is to lay them out to their finished measurements so they will hang nicely when worn. The same concept would apply when you wash the finished cardigan, either by hand or machine. After washing, you can lay it out flat on towels to dry, making sure the garment is not stretched out of shape as it dries. I hope this helps, and I hope your cardigan turns out great!

    Could a thinner yarn like lion brand mandala be used for this cardigan?

    Reply
    • Yay for Yarn

      Hi Ava! Yes, you could use a thinner yarn if you altered the pattern a little bit. Since this cardigan is made from 2 rectangles, it is not too difficult to modify. Just choose a hook size that creates a fabric that looks and feels the way you want with your yarn, and begin with an odd number of stitches that gives you the correct finished length for the panel. You can then work the rows in the stitch pattern, stopping when the panel is the correct width for the pattern. I hope this helps!

    Hi,

    Lovely pattern-thank you! I have never made myself a crocheted garment before. Unfortunately, I must have messed up my tension as the two rectangles are not the same length. Any solutions you can give…other than ripping it all apart? It’s a fun pattern!
    Thanks-Debbi

    Reply
    • Yay for Yarn

      Hi Debbi! If the two rectangles are not the same length, the solution will depend on how far “off” they are from each other. If the one rectangle is only slightly shorter (like an inch or so), than blocking can help get it closer to the right size and you could use it without unraveling and starting that panel over. If the one rectangle is several inches shorter than the other, then, yes, you would need to do it over again or the one side of the cardigan will be shorter, and it might also pull a bit on the other rectangle. I hope this helps, and I hope your cardigan turns out great!

    I love this cardigan! The pattern is so well written and easy to follow. Unfortunately for me, my rectangles didn’t turn out the same size. I think I must have an issue with gauge and consistency! I’ve been crocheting for 45 years and this is the first time I’ve made a garment for myself. I may just try one of the rectangles again. I appreciate all the hard work you did to create this beautiful cardigan.
