Lesson 1

Selecting Your Fabrics

Discover the perfect fabric for your Morris Blazer! This pattern requires fabrics with stretch — either stretch wovens with lycra or stable knits with 2-way stretch. Learn about stretch requirements, fabric weight, and why tricot fusible interfacing is essential for maintaining your blazer's comfortable stretch and drape.

Stretch Wovens

For a woven Morris, look for fabrics with lycra or similar elastic fiber content. Stretch wool suiting is ideal as it drapes beautifully, looks polished, and allows comfortable movement without restriction. You want fabric that stretches horizontally about 2-3 inches when pulled. Example: 96% wool, 4% lycra gives the perfect amount of stretch and recovery.

Stable Knits

Choose stable knits with 2-way stretch that runs crossgrain (selvage to selvage). Avoid 4-way stretch as it can cause drooping and sagging against the facing. Look for knits with body that are thicker than t-shirt weight. Ponte, French terry, and some double knits work perfectly. If using 4-way stretch, consider fusing a second set of front facing pieces to the blazer front for stability.

Fusible Tricot Interfacing

The Morris requires tricot (knit) fusible interfacing to maintain the garment's stretch. Unlike woven interfacing, tricot moves with your fabric, preserving the comfortable stretch that makes this blazer special. Choose tricot fusible in a weight appropriate for your fabric.
