Granny Square Cardigan Steps
Step 1: Make Your Granny Squares
Each square is made with:
Round 1: Start with magic ring or CH 4 and join.
CH 3 (counting as first DC), work 2 DC, CH 2
(3 DC, CH 2) repeat 3 more times
SL ST to join (you now have 4 clusters and 4 corners)
Rounds 2–4 (or more):
CH 3, 2 DC in corner space, CH 2, 3 DC in same space
(3 DC in next space, 3 DC CH 2 3 DC in corner) repeat
Continue on until you have your desired square size
Make 16–24 squares depending on design and size!
Step 2: Square Arrangement and Joining
Design tip for a small/medium cardigan:
4 squares per front panel
4 squares for the back
2 squares per sleeve (or extra ones for longer arms)
Join squares using SC or SL ST in back loops only for an
invisible join.
Step 3: Sleeves
Fold your piece and attach squares to sides for sleeves
Sew underarm and side seams
You can also crochet around the arm opening to extend
sleeves in one color
Step 4: Add the Border
SC or HDC around the entire cardigan (front opening, neckline,
and bottom)
Add 2–3 rows to make it sleek and thick
Optional: Add buttons or a tie front!
