FREE Crochet Summer Cardigan Pattern in Sizes XS-3XL

Everyone needs a good crochet summer cardigan pattern – am I right? Usually, crocheters focus on sweaters and cardigans in the cooler months…but personally I love a good warm-weather cardigan! That’s exactly why I designed the Midsummer Cardigan!

Find the free crochet pattern instructions below, or purchase a print-friendly, ad-free PDF here.

I have to tell you the story of this cardigan before we jump into any details. It was NOT an easy road getting this pattern published by summer time.

I ordered the beautiful deep purple yarn a few months back, started on the design, and was making great progress. However, several major roadblocks caused me to put the project on “time out”

First, I ran out of yarn. I ordered more from We Crochet…and when it came, I realized I had ordered the wrong color. UGH!

Then, after I finished an entire front panel, I realized that one of the balls of yarn I did have had a weird coloring to it that made the panel look different from the other panels.

After getting past these 2 roadblocks, I was sewing everything together and realized I had done the shells on the wrong side of one of the panels!

Let’s just say, I might have “fudged” that mistake a bit and by sewing the panel on the opposite way so the shells matched😂😂

Anyway, I tell you this story just because I love to keep things real around here! Even designers make mistakes…lots of them.

Thankfully, in the end I can finally present to you a brand new summer cardigan crochet pattern. Meet, the Midsummer Cardigan!

Crochet Summer Cardigan Pattern

The Perfect Crochet Summer Cardigan Pattern

This pattern is inspired by a summer night – where I live, we get amazing summer sunsets! I really wanted to design something reminiscent of the deep purple glow in the sky right before the sunset turns to the black night sky.

Thankfully, just because it is pretty doesn’t mean it is hard to make! This summer cardigan is simple, yet elegant and beautiful. With the Midsummer Cardigan, I’ve included a statement border with large triple-crochet shell stitches. The best part is, this border is included in the panels themselves – no need to do any extra work after the seaming and blocking portion!

Of course, those same shells will be incorporated as a border on the short sleeves as well.

How do you crochet a Short Sleeve Cardigan?

Speaking of short sleeves – cardigans with short sleeves are very easy to make! They are made in the same exact way as long sleeves…you just don’t have to crochet as long!

In the case of the Midsummer Cardigan, we will be making 3 rectangular panels, sewing them together, and then working around the armholes to make the short sleeves. We won’t decrease as much as regular sleeves do, so that we end up with a flowy, loose short sleeve that drapes amazingly over the upper arm.

Lightweight Cardigan (made with sport weight yarn!)

Another very important factor of a crocheted summer cardigan is that it is lightweight and breathable. I chose to make the Midsummer cardigan with one of my favorite sport weight yarns – We Crochet Galileo! This yarn is a lovely blend of bamboo and merino wool, which makes for a light and bouncy cardigan.

Of course, you can substitute for other yarns, but I would advise you to choose something that has a good portion of cotton, bamboo, or another plant-based fiber in it. This will allow the cardigan to be much cooler for summer.

I chose Galileo because it is breathable but also has just enough warmth with the merino wool added in.

Mid-length (but adjustable!)

As far as the length of this cardigan, the good news is it is very easily adjusted! I made my cardigan to fall just below my hips. There will be instructions within the pattern for how to adjust the length to make it perfect for you! You could even make it into a cropped crochet cardigan if you really wanted to.

MORE CROCHET CARDIGAN PATTERNS

Notes:

  1. Ch 4 at beginning of rows counts as a tr.
  2. Cardigan is made from 3 panels: 1 back panel and 2 front panels. Pieces are sewn together and then sleeves are joined at the base of the armhole and worked in the round.
  3. When the pattern refers to the “left” and “right” panels of the cardigan, this refers to the position when the cardigan is laid out flat (NOT the position when you’re wearing it).
  4. All pieces of the cardigan start with a foundation single crochet row (fsc). If you are unfamiliar with this technique, check out this blog post. Starting with a regular chain stitch is not recommended because it won’t be as stretchy. But if you need to start with a chain, just be sure to add one more chain to your starting row number. Then, skip the first chain and work one row of sc across (this will give the same result of fsc, just less stretchy).

Abbreviations/Stitches Used:

Chain – ch

Slip Stitch – sl st

Single crochet – sc

Double crochet – dc

Triple crochet -tr

Repeat – rep

Round – rnd

Skip – sk

Stitch(es) – st(s)

Space – sp

RS – right side

YO – yarn over

Special Stitches:

Triple Crochet Shell (tr sh): Tr into indicated st. (Ch 1, tr in same st) 4 times. 

Triple Crochet 2 Together (tr2tog): *YO twice, insert hook into next st. YO, pull up a loop. (YO, pull through 2 loops) twice. Rep from * once more. YO, pull through last 3 loops on hook.

See schematic below for help with seaming.

FINISHING

Wet block your cardigan to the finished measurements listed. To be sure it turns out the right size, you may want to block it out an inch or two BIGGER than listed, because it will tend to shrink back a bit after removing pins (this is at least true when using Galileo yarn).

Here’s what mine looks like blocking:

After blocking, weave in your ends!

I hope you enjoyed this crochet cardigan pattern for summer. I certainly had fun (and quite the adventure!) designing it!

    1. Thank you! I think it would work pretty well – it just wouldn’t be as stretchy as a bamboo/wool. Just make sure to obtain gauge too!

  1. I love that the beautiful edging is worked into the design not added separately! Brilliant!
