If you're drafting 1800s sleeves from period sources and your muslins keep coming out wrong, it's probably not your sewing — it's your research pipeline.

Most historical costumers jump straight from a fashion plate to a pattern draft. They skip the critical steps: verifying measurement systems, cross-referencing across multiple primary sources, and setting up proper digital tools for parametric drafting.

"1800s Sleeve Silhouette Pattern Research: Tools, Setup & Troubleshooting" is a 5-module course that builds the complete pipeline:

✅ The full 1800–1899 sleeve silhouette timeline with construction-critical details

✅ Digital archive navigation — fashion plates, drafting manuals, extant garment databases

✅ CAD setup with Valentina for parametric period pattern drafting

✅ Era-specific construction for Regency, Romantic, Mid-Victorian, Bustle, and 1890s sleeves

✅ Diagnostic troubleshooting framework for common fit problems

✅ Measurement conversion guides (French pouces ≠ English inches — and yes, it matters)

Built for costume designers, historical reenactors, theater wardrobe professionals, and fashion history students who need accuracy, not approximation.
