Weight: This refers to the thickness and density of the interlining, measured in grams per square meter (gsm). Here's a quick guideline:
Lightweight (20-60 gsm): Perfect for summery fabrics or areas that need a touch of structure without losing drape (think shirt yokes or lightweight jacket facings).
Mediumweight (60-100 gsm): The workhorse option, ideal for most general-purpose interlining needs in garment type construction (like collars, cuffs, and waistbands).
Heavyweight (100+ gsm): For those heavier fabrics and outerwear projects where serious structure is required (think winter coat collars and structured jackets).
Material: Woven interlinings come in various materials, each with its own properties:
Hair Canvas: A classic choice for tailored jackets and blazers, offering excellent shape retention and a natural drape.
Cotton: A natural, breathable option for lighter-weight applications, ideal for maintaining a softer hand in your garment type.
Polyester: A popular and versatile choice, offering good structure and stability at a more affordable price point.
