Crochet Sunflower Cardigan - BACK VIEW 

Ever since I started making anything with the sunflower granny square I have been in love with it, and when I made the sunflower bag, I dreamed of crocheting a fabulous sunflower square cardigan. So when I was asked to crochet a sunflower cardigan. I jumped at the chance. I have written out how I crocheted the sunflower squares, and the half squares and will talk you through the construction, and layout of the cardigan. 

TO make the Sunflower crochet cardigan, you will need 22 FULL Squares

and x 2 Triangle  Pieces.

Crochet Triangle Granny for the sunflower cardigan (FRONT) 

Once my cardigan was all sewn together (note I originally made the cardigan a LOT bigger /longer)  but after consultation, the customer wanted a more bomber style (shorter) cardigan.  

I then finished off around the cardigan by slip stitching up the front, around the neck, and slip stitch down to the bottom again, this gives you a lovely neat finish and when working the simple ribbed border, you will slip into each of the slip stitches to connect the ribbing to the cardigan neatly. 

So make sure the original SLIP STICH around the front and neck of the cardigan is as LOOSE as you can make it (even use a hook size up) This adds to the look and will appear professionally finished. 

I have written out the pattern on this page for the FULL sunflower Squares, and the written pattern from the Triangle Sunflower half squares as I wanted a more fitted look at the front of the cardigan. 

If you are a beginner at crochet You will need the  Easy sunflower granny square free crochet pattern, which includes step-by-step pictures to help you make the first few rounds. 

How to crochet a cardigan in the right size. 

I played around with the sizes of the square and hook sizes and decided I wanted quite a baggy crop top for a size 16 PLUS size UK (LARGE BUST)  (although please note pattern terms used are written in the US) 

I used these measurements to work out the size of the square needed 

1. Cross Back- Measure from shoulder to shoulder. ( divide by 4) ADD this number to the original measurement and then divide by 4 again. = measurement required for individual SQUARES. 

 (I  wanted a very loose cardigan so I made my squares BIGGER than this measurement) 

2. Arm Length- With the arm slightly bent, measure from armpit to wrist.

3. Upper Arm- Measure around the widest section of the upper arm located above the elbow.

4. Armhole Depth- Measure from the top outside edge of the shoulder down to the armpit.

5. Waist- Measure your waist at the smaller circumference of your natural waist, usually just above the belly button.

How many Squares Do you need to Crochet A sunflower Granny Square Cardigan 

For this sunflower granny square cardigan, You will require

  •  22 FULL SQUARE Sunflower Granny Squares 
  •  2 HALF Granny Squares, 
  •  2 Under arm Gusset inserts. 

I have made the cardigan without the gussets and just used 6 squares for the sleeves but We hated how it sat and pulled you around the underarm, so the solution was a little bit of creative crochet, I will explain later how to crochet the Under arm gusset.

How to Sew all your Squares and Triangles together to make a cardigan. As I said I started out making a longer cardigan and had taken photos of the longer style, however after consultation with the customer they wanted the short bomber-style cardigan. So I have no images of how I put this cardigan together. 

However, I have made some graphics of the layout so you can still make the cardigan. 

NOTE: these Graphics can be saved to your computer so please click on them to enlarge to read
I find it a nicer finish if I hold the 2 sides of the squares together and sew over the BACK loops of each sides stitches together  together 

You will require 20 FULL Sunflower Granny Squares in Total and 2 HALF Granny Squares. Lay them out as shown and pin them in sequence before sewing. You can also check it will FIT here, by measuring when all together.

How to construct the  Sleeves for the Cardigan is as follows. 

How to crochet a Sunflower Granny Square Cardigan FREE Crochet  Pattern - LisaAuch Crochet


I joined my white yarn at C on the MAIN cardigan on the underarm (see Graphic on MAIN BODY for C placement) 
working in Double Crochet ALONG the row, ch2, TURN. 
Skip first st, and work Dc in each stitch to the end. Repeat Until you have 2 stitches left. This should measure the length of 2 squares. 
Pin into Position and SEW together by connecting the sides of the sunflower squares and the raw edge of the triangle just made. A-A, and B-B as shown, if you have no stitches left, just keep sewing the sides together until no stitches are left. SEE the image below (this is a VIEW of how the underarm should look when sewn together)

How to crochet a neat ribbed border around your cardigan. 

I always make the LOWER part of the ribbed border 
To start ensure the Right side of the cardigan faces you
Join yarn and work LOOSELY around the bottom of the cardigan. In the same Yarn slip stitch along ALL the stitches of the squares to the next side. Ends with a slip st into the VERY last space. DO NOT FASTEN OFF 

EASY Crochet Ribbing Pattern for Cardigan

Chain 11, working INTO the second chain from the hook Slip stitch back along the chain just made, Slip to join INTO the next slip st,  (10sts) 
Ch1, working INTO the second chain from the hook and in the back loops of the previous row's stitches to end, 
Ch1 TURN, working in back loops  Slip stitch back along the row,  Slip to join INTO the next slip st,  (10sts) 

Repeat in every stitch around. Do not fasten off 

Again ensuring the right side of the cardigan is facing you, slip stitch EVENLY and LOOSELY up the front of the cardigan and, around the neck edge, and back down to the bottom. 

You will be working the ribbing exactly as before, however, you will want to place buttonholes. you can choose which side and at what spacing you prefer them. 

To crochet  a buttonhole for the Cardigan 

Ch1 slip st in the next 4 sts, chain 3, and slip stitch into the rest of the stitches until the end, TURN Ch1, and work a slip stitch in back loops of all stitches. 
This technique gives a perfect edge, now you see why we slip stitches along the side of the Half Sunflower, It creates such a clean edge. 

Fasten off and WEAVE in ALL ends securely.
