Special Notes

1. Sizing: Adjust the size of your sweater by adding or reducing the starting triangle rows or sleeve length. The number of rows required for each section will depend on your measurements.
2. Gauge: Not critical, but 4 rows of the granny triangle = approximately 4 inches.
3. Panel Construction:
   • This project requires 3 panels: one front panel, one identical back panel, and two sleeves.
4. Yarn Management for Color Changes: Always attach new colors at the end of a row. Cut and secure yarn responsibly to avoid unraveling.

Step-by-Step Instructions

Triangle Granny Square Front/Back Panels

Foundation – Starting the Granny Triangle:

1. Make a Magic Ring:
   • Wrap yarn around your finger to create a loop, insert hook, pull through, and make a loop. Secure tightly.
   • Alternatively, use the chain-4 and slip stitch into the first chain method to form a loop.
2. Row 1:
   • Ch 4 (counts as dc + ch 1).
   • Into the magic ring, work:
     • 3 dc.
     • Ch 2.
     • 3 dc, ch 2. Repeat 3 more dc, ch 2.
   • Ch 1, dc back into the magic ring.
   • Close the ring tightly by pulling the tail of the yarn.
     Save
3. Row 2:
   • Ch 4, turn.
   • Into the first ch-1 space, work 3 dc. Ch 1.
   • In the first ch-2 space (center of the triangle), work: 3 dc, ch 2, 3 dc.
   • Continue across: Ch 1, work 3 dc in each ch-1 space.
   • At the last chain space, work dc to complete the row.
     Save

Building the Triangle: Repeating Rows

4. Repeat Row 2, adding additional rows, to increase the size of the triangle.
   • The triangle grows wider with ch-1 spaces and 3 dc clusters on each side of the center.
5. Continue until the shoulder-to-shoulder measurement is reached plus 2-3 inches for ease.
   • For a Large size: Work 15 rows to reach 21 inches wide.
     Save

Making the Bottom Edge Straight

6. Straight Row Decrease: Start straightening the sides to create a square bottom (no increases):
   • At the beginning of the row: Ch 2 (not ch 4), skip the first space, make 3 dc into the next ch-1 space.
   • Work as usual across, but end with 1 dc in the last ch-1 space.
7. Continue repeating straight-edged rows until the front panel is your desired length (e.g., 20½ inches).
   Save
8. Change Colors (Optional): Add secondary colors to create stripes or contrast. Attach new yarn at the last stitch of a row to keep the colors seamless.

Back Panel

9. Make the Back Panel identical to the front panel, repeating the same steps.
10. The back panel can be made in one solid color for variation.

Sleeves

11. Construct the sleeves using the same granny triangle method, but work for a shorter height and width.
    • Example sleeve size: 16½ inches wide, with 20 rows.
12. Continue straight rows until the sleeve measures the desired length.
    • Add ribbing for 2-3 extra inches. The full length may measure 14-16 inches in the widest part.

Assembly

Joining Shoulders

13. Place the front and back panels together, wrong sides out. Align the shoulder edges evenly and secure with stitch markers.
14. Leave neckline space (e.g., 9-inch gap) and join 6 inches on each side of the shoulders using single crochet (sc) stitching.
    Save

Attaching Sleeves

15. Align each sleeve with the armholes, ensuring the center of the first row matches the shoulder seam.
16. Attach with sc stitches around the armhole, ensuring the stitches align evenly on both sides.

Seaming the Sides

17. With the sweater still inside out, seam together the sides starting from the sleeve opening down to the bottom hem. Use the same sc seaming technique.

Ribbed Edges

Neckline Ribbing

18. Attach yarn to the neckline and work around the opening:

• Row 1: 2 dc in each space around the neckhole.
• Rows 2-4: Alternate 1 FPdc and 1 BPdc to create ribbing.
• Add more rows if you’d prefer a turtleneck or higher collar.

Cuff Ribbing

19. Work across the sleeve hem:

• Row 1: Dc evenly around the wrist opening. Adjust tension so your hand fits.
• Rows 2-13: Alternate FPdc and BPdc to create the ribbing.
  Save

Bottom Ribbing

20. For the hem of the sweater:

• Work 2 dc in each space around the bottom edge, including side seams.
• Continue alternating FPdc/BPdc for 4 rows (or longer if desired).

Finishing

1. Weave in all loose ends using a darning needle.
2. Block the sweater to smoothen edges and even out dimensions.
3. Optional: Trim excess yarn or add tassels/fringes for flair.

Conclusion

Congratulations on completing your Granny Square Sweater! This versatile sweater is both cozy and attractive, making it perfect for layering during cooler weather. With an accessible yet customizable design, this pattern offers endless opportunities for personalization.

Pattern Corrections

If the sweater sides feel uneven after assembly:

1. Block carefully to align panels before joining.
2. Adjust row counts or remove clusters if edges are misaligned.

Tips

• Use stitch markers liberally to ensure all seams align during assembly.
• Keep your stitches loose for a stretchy, comfortable fit.
• If the neckline feels tight, add additional rows or leave extra space during seaming.
