Description
Pellon SF101 Shape-Flex is the all-purpose woven cotton fusible interfacing, the one our customers buy more than any other. Because it is woven rather than non-woven it moves with the fabric and gives a crisp, clean finish without feeling stiff or papery. Fused to light to medium woven and knit fabrics it firms up collars, cuffs, yokes, pockets, facings and other detail areas, and it is the standard interfacing for bag making and for backing needlework and punch embroidery.
It is intended for fabrics such as oxford cloth, chambray, gingham, madras, tattersall, pincord, flannel and polyester/cotton blends, and it is the interfacing most quilters use to stabilize t-shirts and knit blocks. Once fused it is machine washable and holds its bond through normal laundering. The 20" x 10-yard bolt in white is the format most of our customers keep on the shelf: wide enough for garment pieces and bag panels, long enough to last through a season of projects, and the lowest cost per yard short of the 60" bolt.

Compare and choose
- SF101 vs 911FF Featherweight: which should I buy?
- SF101 is a woven cotton with body; 911FF is a featherweight non-woven polyester that nearly disappears. Choose SF101 for collars, cuffs, bags and anywhere you want crispness and a fabric-like hand. Choose 911FF for sheers, soft blouses and light support you should not be able to feel. Pellon 911FF Featherweight 20" x 10 yd
- Which side is the fusible side?
- The fusible side has the slightly rough, bumpy adhesive dots; the other side is smooth woven cotton. Place the dotted side against the wrong side of your fabric and press with a hot, dry iron using firm pressure for several seconds across the whole piece, lifting and moving the iron rather than sliding it.
- Do I need to pre-shrink SF101?
- It is 100% cotton, so it can shrink a little. If the project will be washed, pre-shrink the interfacing by soaking it in warm water, letting it drip and drying it flat before fusing, or at least pre-wash the fashion fabric so both layers have shrunk once. For bags and items that will not be laundered, fuse it straight from the package.
- Is SF101 right for a t-shirt quilt?
- Yes, it is the interfacing most t-shirt quilt instructions call for. Fuse it to the back of each shirt before cutting so the knit stops stretching, then square up and piece as usual. It keeps the blocks soft enough to quilt and stable enough to sew straight.
- SF101 vs Craft-Fuse 808 or Decor-Bond 809 for bags?
- SF101 gives fabric body and a crisp hand while staying flexible; it is the choice for bag exteriors, linings and pockets that should still fold and drape. Craft-Fuse 808 and Decor-Bond 809 are stiff non-wovens for structure that holds a shape, such as box bags and bins. Many bag makers fuse SF101 to the fabric first and add foam or Decor-Bond on top of it. Pellon 808 Craft-Fuse 20" x 10 yd
- 20" bolt or 60" bolt?
- The 20" bolt suits garment pieces, pockets and most bag panels, and it is the easier size to store and cut from. Buy the 60" bolt when you fuse whole bag exteriors, large totes or yardage, or when you want fewer seams in big pieces; it costs more per bolt but less per square foot.

- White or black Shape-Flex?
- Match the fabric. White is right under light and medium colors. Under black, navy and other dark fabrics, white interfacing can shadow through at facings and seam allowances, so use the black bolt. The interfacing itself is the same. Pellon SF101 Shape-Flex 20" x 10 yd, black
- Which side is the fusible side?
- The fusible side has the slightly rough, bumpy adhesive dots. Place that side against the wrong side of your fabric and press with a hot iron to bond.
- What fabrics is it best for?
- Light to medium wovens and knits such as oxford cloth, chambray, gingham, flannel, quilting cotton, and cotton-poly blends.
- Is it washable?
- Yes. Once fused, Shape-Flex is machine washable and holds its bond through normal laundering.
