Product details, sizing & instructions

Pellon SF101 Shape-Flex® is one of our most popular and trusted interfacings, loved by quilters, bag makers, garment sewists, and embroiderers for its beautiful balance of stability, softness, and professional results.

This all-purpose woven fusible cotton interfacing provides crisp support and reliable structure while still allowing fabric to maintain a natural drape. Designed for light to medium-weight fabrics, SF101 fuses smoothly with a warm iron and adds gentle body without excessive stiffness or bulk.

Perfect for collars, cuffs, facings, pockets, waistbands, bag panels, quilt blocks, and embroidery stabilisation, Shape-Flex® has become a go-to favourite in countless sewing rooms and is frequently recommended in designer sewing and bag-making patterns.

Unlike many non-woven interfacings, SF101 features a woven construction that moves naturally with fabric, helping projects feel softer, smoother, and more professional. It is especially popular in bag making where sewists want clean structure and stability without needing heavier stabilisers or foam products.

It also works beautifully as a backing for embroidery, punch needle, and decorative stitching projects where extra support is needed to reduce stretching and distortion while stitching.

Machine washable, tumble dry safe, and suitable for dry cleaning, Pellon SF101 continues to perform beautifully even after repeated laundering.

Used this on the back & sides of a fabric wall hanging that I made. The black finish highlights my work beautifully. I like that it's cotton, too. This product was easy to use. It was neatly packaged & delivered promptly. Winning!
