Some fabrics need support, but they refuse to hold still for it. A blouse fabric drapes, a dress fabric flows, and a lightweight suiting moves a little in every direction — add a stiff, non-stretch interfacing and the garment suddenly feels like someone else's clothes. Pellon® 865F Bi-Stretch Lite™ Interfacing solves that mismatch. It is a lightweight woven fusible interfacing with two-way stretch, so it adds soft support while still moving with the fabric it is fused to.
What This Interfacing Is
Bi-Stretch Lite™ is a fusible interfacing made from 100% polyester and sold on a 20" x 10 yard bolt in white. Pellon describes it as sheer and silky, offering a luxurious hand and soft support. Those two words — sheer and silky — tell you a lot. This is not a crisp, board-like stabilizer for collars that must stand at attention. It is a light, smooth layer that disappears behind your fashion fabric, steadying it without changing how it feels against your skin or how it falls from your shoulders.
Because it is woven and stretches in both directions, it behaves more like fabric than like paper. A non-stretch interfacing locks a piece in place, but Bi-Stretch Lite™ gives a little in both directions, so it supports a garment's shape without fighting its natural movement.
What It Is Best For
Reach for Bi-Stretch Lite™ in blouses, dresses, and lightweight suit fabrics — the projects Pellon names for this product. It suits the areas that benefit from a whisper of extra body and stability, and full garment sections where you want soft support rather than structure.
It also fuses easily to hard-to-fuse fabrics such as rayon and acetate. Those slippery fabrics often need gentle support yet can be frustrating to interface. A lightweight fusible that bonds readily to them, without bulk or stiffness, earns its place in a garment sewist's stash.
How to Use It
Test first. Before you fuse a full piece, fuse a small scrap of interfacing to a scrap of your fashion fabric. Check that the hand still feels right, that no adhesive shows through the sheer fashion fabric, and that the two layers move together. With rayon and acetate especially, a test tells you more than any guess.
Cut with the stretch in mind. Cut your interfacing pieces to match your fabric pieces, keeping the direction of stretch consistent from piece to piece so both sides of a garment behave the same way.
Fuse in steps. Place the interfacing on the wrong side of your fabric, adhesive side down, and press section by section with your iron rather than sliding the iron across the surface — lifting and pressing helps you get a smooth, even bond without shifting the sheer layers. Work across the whole piece, then turn it over and press lightly from the fabric side. Let the fused piece cool flat before you move or sew it, so the bond sets and the layers stay smooth.
Sew as usual. Once fused, treat the fabric and interfacing as a single layer when you construct your garment. The support is now built in, so your seams, darts, and hems get the benefit without an extra loose layer sliding around inside.
Tips and Care
Match weight to weight: Bi-Stretch Lite™ is a lightweight interfacing, so save it for light fabrics and do not ask it to do the heavy work of firm tailoring — a garment that needs crisp, rigid shaping needs a firmer product. Keep your fashion fabric's care in charge of the finished garment, and handle fused pieces gently before sewing so you do not stretch them out of shape on the cutting table.
Above all, judge this interfacing by what it does not do: it does not stiffen, it does not flatten drape, and it does not stop a flowing fabric from flowing. It simply helps that fabric hold a better shape, for longer — which is exactly what a good blouse, dress, or lightweight suit deserves.
