Sewing enthusiasts and aspiring tailors, this horsehair canvas interfacing is that secret ingredient that takes your garment construction from homemade to professionally tailored! This 2-yard package gives you plenty of material to work with for multiple projects, and the 20-inch width is perfect for most jacket and coat patterns. The medium weight provides just the right amount of structure and body without making your garments feel stiff or cardboard-like. The blend of 41% acrylic, 9% hair, 26% polyester, 14% rayon, and 10% cotton creates a versatile interfacing that shapes beautifully while maintaining some flexibility. As a sew-in rather than fusible interfacing, it gives you more control during construction - you can baste it in place, test the drape, and make adjustments before final stitching. I've used this for blazer collars, lapels, and front facings, and it creates that crisp, professional shaping that store-bought jackets have. The horsehair content provides natural resilience and memory that helps garments maintain their shape over time. It's particularly great for structured pieces like tailored jackets, coats, and even some structured dresses where you want clean lines without bulk. The quality is noticeably better than cheaper craft interfacings - it handles sewing well without fraying excessively and presses beautifully. Whether you're a serious tailor or a home sewer looking to upgrade your skills, this interfacing helps you achieve those polished results that make people ask 'Where did you buy that?' when you made it yourself!
