Sleeve Pattern Drafting: Basic Long & Short to Bell & Trumpet Sleeves

Learn how to draft basic sleeve pattern (long and short) and trumpet/bell sleeve pattern from scratch. You will learn how to draw precise basic long and short sleeve patterns using simple body measurements, and then use those core blocks to derive stylish flared variations like bell and trumpet sleeves. This course focuses entirely on flat pattern making, giving you the technical foundation to design custom sleeve shapes with confidence before you ever cut into fabric.

What You Will Learn

• Drafting Basic Short Sleeves: Draw a clean, well-fitting short sleeve pattern block step-by-step using standard measurements.

• Drafting Basic Long Sleeves: Map out a full-length sleeve block with accurate sleeve length ratios and elbow points.

• Deriving Bell/Trumpet Sleeves: Manipulate your pattern to create a fitted upper arm that flares out dramatically near the elbow or wrist.

• Pattern Finishing & Markings: Add seam allowances, draw accurate grainlines, and mark alignment notches so your drafted patterns are complete and ready to use.
