Pattern Correction & Tips

1. Count Regularly: Ensure cluster and corner counts match between front and back panels.
2. Sl St Joins: Slip stitches can be tight; use a slightly larger hook if pulling is difficult.
3. Ribbing Fit: Test ribbing lengths before attachment to ensure snug yet comfortable fit.
4. Customize Sizing: To increase size, simply add more granny square rounds to the body panels and sleeve length/width.
5. Keep Sides Aligned: Always align panels and sleeves from the center outwards to avoid uneven joins.
6. Try On as You Go: Modular construction allows you to check fit at each stage.
7. Color Transitions: When changing colors, weave in ends as you go to minimize finishing work.
