Special Notes

• Squares are worked using triple crochet (tr) granny clusters for a lacier, larger motif.
• Gauge is important. Adjust square size to get desired fit: each Square should be approximately 6.5" (16.5cm) x 6.5" (16.5cm) for a standard adult medium. Adjust the number of rounds or hook size as needed.
• All yarns used for the sweater should be of the same weight for uniform sizing and appearance.
• Joining method: Slip stitch join with RS facing together for durable seams with a slight stretch.
• The pattern can be adapted for other sizes by adjusting the number of squares, square size, or layout.

Sizing & Measuring

1. Bust measurement: Measure around the fullest part of your torso.
2. Ease: Add 2" (5 cm) to your bust measurement for comfort.
3. Front/Back Panel Width: Divide eased bust measurement by 2.
4. Square Calculation: Divide Panel Width by 3 – aim for that size per granny square (round to nearest logical value, e.g., 6.5”).
5. Length: Measure from armpit to waist or desired length. You will use 2 squares for body length (for cropped), or add extra rows/rounds if you want longer.
6. Sleeve squares are made larger: add one extra round of border to 8 of the squares.

Pattern Corrections & Tips

Corrections

• Square measurement: If your squares are smaller or larger than needed, adjust the number of rounds or your hook size. Each must be square—measure both width and height.
• Slip Stitch Seam: Always work with RS together to hide seam on inside.

Tips

• Color Coordination: Using a multi-color cake or pre-matched color palette makes color selection easier.
• Blocking: Strongly recommended. It shapes squares, improves drape, and assists assembly.
• Fade or ombré effect: Plan your color order before you start.
• Customize: Try a cardigan (add opening, edge with buttons), different sleeve lengths, or border variations.
