Granny Stitch Polo Shirt

This Granny Stitch Polo Shirt merges classic granny clusters with crisp shaping and a tailored collar, resulting in a comfortable, breathable, and stylish garment suitable for warm weather. Featuring neat lines, modular construction, and customizable sections, this pattern creates a versatile shirt with a vintage touch. The bamboo cotton yarn ensures a lightweight, silky feel and superior drape, while the alternating stitches produce visual and textural interest. The design’s modularity makes it easy to adapt to individual measurements for a personalized fit.

Pattern Basic Points

• Classic Construction: Separate front and back panels are worked flat, then shaped and joined.
• Iconic Granny Clusters: The body is built with rows of 3-double crochet clusters and open chain spaces.
• Polo Neck Detailing: Unique split neckline and established collar transform the shirt for modern polish.
• Refined Edges: Ribbed-style cuffs and hem bring structure with front and back post stitches.
• Fully Adjustable: Starting chain, row repeats, and shaping are easy to modify for different body measurements or style preferences.

Special Notes

• Chains must be made in multiples of 4, plus 5 extra, to maintain stitch pattern continuity.
• Measure yourself for your preferred fit, remembering the bamboo cotton provides stretch and is best blocked to shape.
• Steam blocking the collar produces a neater turn and a more professional finish.
• Fit can be altered by adjusting the number of foundation chains and the number of body or sleeve rows, as well as by customizing the armhole and collar depth.

Skill Level

Intermediate

Familiarity with working granny stitch, shaping through increases and decreases, working post stitches, and basic seaming is required. Some experience with garment construction will be helpful, especially for the collar and sleeve shaping.

• Hooks: 3.5mm (main body), 3.0mm (cuffs and finishing)

Measurements / Sizing

• Width: Foundation chain determines shirt width; e.g., 120 + 5 chains (~125) can fit a standard S/M. Add or subtract by increments of 4 chains for width adjustments.

  • Place back and front panels together, matching rows and edges.
  • Using slip stitches, join at sides, leaving an 8″ gap at the bottom of each armhole.

  • Fasten off and weave in ends.

4. Sleeves and Finishing

• Bottom Hem
  • Repeat cuff instructions at shirt base (switching to 3.0mm hook), working 2 rounds of fpdc/bpdc ribbing for a clean hem.
• Blocking
  • Steam iron collar lightly to set shape and ensure a crisp, flat edge.

Assembly

After all pieces are completed:

1. Weave in all loose ends using a darning needle.
2. Block the finished shirt to measurements, focusing on opening the granny stitch and smoothing seams.
