One of the great things about the granny square cocoon cardigan is that it can be made in just three simple steps by anyone who has mastered basic crochet skills: chain stitch, slip stitch, single crochet and double crochet.
Another great thing about this pattern is that it’s so forgiving that gauge doesn’t matter. To get the correct size, all you need to do is make your granny square at least half as tall as the intended wearer of the cardigan, plus an extra inch or two. That’s step one.
To get the correct size, all you need to do is make your granny square at least half as tall as the intended wearer of the cardigan, plus an extra inch or two.
Step two is to fold the granny square in half and stitch up the side seams, leaving openings for armholes. Step three is to add a border of six rows of single crochet around the armholes and the front opening. That’s all there is to it!
The sample cardigan shown here, intended to be worn by someone who is 5’4″ (64″) or shorter, is based on a 33″ granny square made from 4 skeins of Lion Brand’s Heartland yarn, which works particularly well for this pattern. (It comes in numerous colors; I used the color “Redwood.”) To make a cardigan for someone taller than 5’4″ using this yarn, I recommend getting 5 skeins.
Here is a two-minute video showing the pattern basics. The written pattern follows below.
Pattern: Granny square cocoon cardigan
Materials you’ll need:
- 4 or 5 skeins of Lion Brand’s Heartland yarn, depending on intended size of cardigan, or 1000-1250 yards of a medium weight (#4) yarn of your choice
- Size J crochet hook
- Measuring tape
- Yarn needle
- Chain stitch (ch)
- Slip stitch (sl st)
- Single crochet (sc)
- Double crochet (dc)
To connect new skeins of yarn, I recommend using the Russian Join, which reduces the number of weave-ins required. Watch this video for a quick tutorial:
Step 1: Crochet a BIG granny square
Ch 6 and join in a ring with sl st.
Round 1: Ch 3 (counts as 1st dc here and throughout), 2 dc in ring, ch 2, * (3 dc in ring, ch 2) 3 times, sl st in top of starting ch 3.
Tip: Lay yarn end along ring and crochet Round 1 over it for an effortless weave-in.
Round 2: Ch 3 and turn, (2 dc, ch 2, 3 dc) in ch 2 space to form a corner, (ch 1, 3 dc, ch 2, 3 dc) in 3 remaining ch 2 spaces, ch 1 and sl st in top of starting ch 3.
Round 3: Ch 3 and turn, (2 dc in ch 1 space), (ch 1, 3 dc, ch 2, 3 dc) in each ch 2 space in corner and (ch 1, 3 dc) in each ch 1 space on side, ch 1 and sl st in top of starting ch 3.
Repeat Round 3 until square reaches desired size.
Final round (“binding”): Ch 1 and turn, sc in each dc and through each ch 1 space on sides; in corners, 4 sc through ch 2 space; sl st in starting ch 1, cut 6” tail and fasten off.
Step 2: Stitch together sides forming armholes
Fold square in half with right sides together to form a rectangle, taking care to align 3 dc clusters and ch 1 spaces to the clusters and spaces on the opposite side.
Note: If you made your granny square using the above instructions in which you turn the work after every round, both sides will probably look pretty much the same, and you can pick whichever side you like best to be the “right” side.
Beginning 7” from fold, single crochet through all loops of “binding” (final round sc) to end of side and through first 2 ch of corner only.
Note: Beginning 7” from fold creates a 14” armhole which will fit most. If necessary, the armhole size can be adjusted smaller or larger by starting the side seam closer to or farther from the fold.
Cut 6” end and fasten off.
Repeat on other side.
Step 3: Add borders.
For the front opening and both armholes:
Round 1: Join yarn with sl st in sc “binding” near one of the side seams made in Step 2, ch 1, sc in each sc of “binding” until you reach ch 1, sl st in ch 1.
Tip: Crochet Round 1 over yarn ends left from binding and side seams for effortless weave-ins.
Rounds 2-6: Ch 1 and turn, sc around front opening until you reach ch 1, sl st in ch 1.
Cut 6” end and fasten off.
Weave in ends. (If you crocheted over all previous yarn ends, and used the Russian join to add new skeins of yarn, you should only have three ends left to weave in.)
