Granny Square Cocoon Cardigan

A super simple but beautiful cocoon cardigan can be made with just 1 large granny square. I love how these look, such a great effect from a simple design. To create a cocoon cardigan you simply fold your square in half and seam up the sides leaving an armhole. However if you like me hate sewing seams check out how I create my cocoon cardigans below using the join as you go method.

Start by creating a large granny square, you can find a tutorial here if you need it, see below chart for sizing ideas although you can modify the square to be the best fit for you.

1). Once you have your granny square at the right size, do not fasten off, you will continue with the working yarn, lie your square out flat and fold it in half ..

2). Starting in the corner that has your yarn still attached you will be working up the short side of the rectangle. Begin by creating half of the corner and then working down the side until you have worked approximately. 2/3rd of the way down the short edge .. (make sure to note down how many blocks you have completed for when you get to the other side. Eg. 12 blocks in the below photo)

3). Once you have worked 2/3 of the way down flip your work ..

4). Now you will start working back up towards the corner, joining the 2 sides as you go.

Begin by working a block in the corresponding space 2/3 of the way down as indicated by the hook in the above photo, then slip stitch in the space between the 2 blocks as noted by the hook in the photo below ..

5). After working the slip stitch you will work a block in the next space on your working side, as noted by the hook in the photo below ..

6). Then slip stitch in the next space between 2 blocks as noted by the hook in the below photo ..

7). Continue working a block on your working side and slip stitching in the corresponding space on the other side until you reach the corner. At the corner complete your full corner and continue working all the way down the next side and complete the next full corner too ..

8). With your work folded in half again you will work down the short side the same amount of blocks you did when joining the other side. (Eg. 12 blocks, see above)

9). Repeat steps 3-6 as above.

10). Continue working a block on your working side and slip stitching in the corresponding space on the other side until you reach the corner. At the corner complete the first half of your corner then ch1, then slip stitch into the corner chsp of the opposite corner, then ch1, then complete the second half of your corner. See photos below ..

11). Continue working down the long side of your work until you reach the half finished corner from the beginning. You will now work the other half of the corner, ch1, slip stitch into the corner chain space of the opposite corner, then ch1, you will then finish by slip stitching to the top of the first dc (or ch3) created at the beginning. See photos below ..

12). Now you can fasten off and sew in your ends, the big bonus here is there are only 2 ends to sew!

Optional finishing touches would be to add edging around the large centre opening or to add edging to the armholes or even to continue with sleeves.

Your cocoon cardigan is now complete. I hope you love it 💕
