Pellon SF101 Shape-Flex Cotton Woven Fusible Interfacing 20in By The Yard
The Pellon SF101 Shape-Flex Cotton Woven Fusible Interfacing — 20" Wide By The Yard is a lightweight woven cotton fusible interfacing — one of the most respected and widely used interfacings in the quilting and garment sewing market. SF101 is 100% cotton, woven construction (with grain), and fusible on one side, providing a natural hand and drape that is unique among fusible interfacings. Its cotton construction makes it the preferred choice for quilters who want a natural fiber interfacing compatible with cotton fabrics.
Top 10 Questions About Pellon SF101 Shape-Flex Cotton Woven Fusible
- What makes SF101 different from nonwoven fusible interfacings?
- SF101 is 100% cotton woven construction — it has a grain line, stretches on the bias, and drapes like fabric rather than like a bonded stabilizer. Nonwoven interfacing has no grain and adds stiffness; SF101 adds structure while maintaining the natural drape of cotton fabric. For quilters who prefer natural fiber materials throughout their work, SF101 is the preferred fusible interfacing.
- Is SF101 appropriate for quilted garments?
- Yes — SF101 is the standard fusible interfacing for quilted garment construction where natural fiber materials and appropriate drape are desired. It provides garment structure without the synthetic feel of nonwoven alternatives.
- Is SF101 machine washable?
- Yes — SF101 is designed for repeated laundering. The cotton construction is compatible with standard quilting cotton care.
- Can SF101 be used for bag construction?
- Yes — for bags where natural fiber materials are preferred and a moderate level of structure is appropriate. For maximum bag rigidity, heavier stabilizers like Soft and Stable or Flex-Foam provide more structure than SF101.
- How is SF101 applied?
- Fusible side to the wrong side of the fashion fabric, iron at cotton temperature with steam or dry press per current Pellon instructions. The woven construction is heat-compatible with cotton fabrics.
- Why buy by the yard?
- By-the-yard purchasing provides exact yardage for specific projects without a full bolt. Ideal for individual garment projects, specific appliqué applications, and projects with a known yardage requirement.
- Is SF101 appropriate for appliqué preparation?
- Yes — fusing SF101 to the wrong side of appliqué fabric before cutting stabilizes the fabric and provides a crisp edge for appliqué shapes, particularly in smaller or more complex designs.
- Does SF101 affect hand quilting needle passage?
- SF101 is lightweight enough that it does not significantly impede hand quilting needle passage, making it appropriate for use in projects that will be hand quilted.
- Is 20" width standard for garment and bag construction?
- 20" is the standard width for most garment interfacing applications. For wider applications, panels can be cut and positioned to cover larger areas.
- Is SF101 the best choice for precision pieced appliqué?
- Yes — SF101’s woven cotton construction provides crisp, stable cutting lines for precision appliqué shapes while maintaining compatible fabric hand throughout the project.
