Need a larger (or smaller) size than your pattern offers? In this step‑by‑step tutorial, Alexandra Morgan of In‑House Patterns shows you how to add one full size to any multi‑sized sewing pattern—without special software or expensive tools. You’ll learn:
✅ How to identify the grade rule already built into your pattern
✅ Where to plot anchor points so the new size remains true to the design
✅ Tips for keeping curves, notches, and pleats accurate after grading
✅ How to repeat the process if you need more than one extra size

This technique works on tops, dresses, skirts, and pants, whether you’re sizing up or down. Master it once and you’ll never set aside a favourite pattern again.
