Granny Squares
Before we start assembling our cardigan, we need to make a total of 64 granny squares. Each square should measure 4 inches by 4 inches, providing the perfect building blocks for our cozy project.
- Back Panel: Crochet 20 granny squares arranged in a grid of 5 squares wide and 4 squares tall.
- Front Panels: Create 20 squares, divided into 10 for each panel, laid out in a 2.5 squares wide by 4 squares tall configuration.
- Shoulder Panels: Make 2 squares, with 1 square for each shoulder.
- Sleeves: Crochet 12 squares, 6 per sleeve, arranged in a 3 squares wide by 2 squares tall formation, allowing for any necessary length adjustments.
Expected Result: At this stage, you should have 64 granny squares ready for assembly.
Join the Squares
Now it’s time to join your granny squares to form the various components of the cardigan. Use a 3.0 mm hook for a tidy finish.
- Join Method: Use a single crochet join to connect the squares. This creates a seamless look.
- Positioning: Place two squares together with the right sides facing out. Ensure they align properly for a neat finish.
- Sew Rows First: Begin by joining all rows of squares together, then connect the rows. This method ensures stability in the structure.
Professional Tip: Use stitch markers to help keep your squares aligned, especially when joining multiple rows.
Assemble the Jacket
With your squares joined, it’s time to assemble the cardigan itself.
- Attach Sleeves: Align the long edge of each rectangular sleeve panel with the corresponding armhole. Attach securely.
- Fold the Cardigan: Match the front panels to the back panels at the sides. Ensure everything is even before securing them.
Expected Result: Your cardigan should now resemble the basic shape, with sleeves attached to the body.
Adding Ribbings
The final touch is adding ribbings to enhance the cardigan’s fit and finish.
- Attach Yarn: Begin at the corner of the hem. Work one double crochet (DC) in each stitch along the bottom edge of the cardigan.
- Sleeve Ribbings: While working on the sleeves, decrease by crocheting 2 DC together every 3-4 stitches to taper them properly.
Professional Tip: Using a slightly smaller hook for the ribbing can create a tighter fit, giving the cardigan a polished appearance.
