Top 10 Questions About Pellon SF101 Shape-Flex Interfacing
Q: What is Pellon SF101 Shape-Flex interfacing used for?
A: SF101 is used to add body and stability to fabric without stiffness. It is the go-to choice for quilt blocks, bag panels, garment facings, collars, cuffs, and any sewn project where you need structure that still moves naturally with the fabric.
Q: Is SF101 fusible or sew-in interfacing?
A: SF101 is a fusible interfacing — it bonds permanently to fabric with the heat of an iron. No sewing required for application, making it fast and easy to use on a wide range of projects.
Q: Is Pellon SF101 good for quilting?
A: Yes, it is one of the most popular interfacings in the quilting world. It is used to stabilize quilt blocks, stiffen quilt labels, back appliqué pieces, and add body to quilted bags and wallets.
Q: What fabrics work best with SF101?
A: SF101 works beautifully with woven cotton fabrics — the most common quilting material. It also bonds well to linen, rayon, and medium-weight woven garment fabrics.
Q: Can I use SF101 on knit fabrics?
A: SF101 is a woven interfacing and does not have stretch. For knit fabrics, Pellon EK130 Easy-Knit is the better choice as it stretches with the fabric.
Q: How do I apply Pellon SF101 to my fabric?
A: Place the adhesive side (slightly rough texture) against the wrong side of your fabric. Press with a dry iron on a cotton setting for 10–15 seconds per section. Allow to cool before moving.
Q: Will SF101 interfacing make my fabric too stiff?
A: No — SF101 adds body and structure while maintaining a soft, natural hand. It is specifically engineered to stabilize without creating the boardlike stiffness of heavier interfacings.
Q: Is SF101 washable after fusing?
A: Yes, once fused properly, SF101 is fully machine washable and dry-cleanable. The bond remains secure through repeated laundering.
Q: How many yards does a 10-yard bolt provide for bag making?
A: A 10-yard bolt at 20 inches wide is sufficient for approximately 8–12 tote bags or 15–20 quilted zipper pouches depending on the pattern size, making it excellent value for regular sewists.
Q: Why is SF101 the best-selling interfacing at Linda's Electric Quilters?
A: Quilters and sewists love SF101 because it is 100% cotton — it behaves like the fabrics they already work with, bonds cleanly, and never creates a plastic or synthetic feel in the finished project. It is the trusted standard for good reason.
