Description
Pellon 805 Wonder-Under is the original paper-backed fusible web and the one most appliqué patterns assume. You trace your shape on the paper, press it to the wrong side of the fabric, cut, peel and press the shape onto the background. The 17" x 10 yard bolt is the shop size: enough for a lot of appliqué, and far cheaper per yard than small packages.
It fuses in seconds and is 100% machine stitchable, and the fabric keeps a soft hand after fusing, which is why it suits quilts and apparel as well as crafts. It bonds fabric to fabric or to any porous surface such as wood and cardboard. For denim, canvas or heavy wool, step up to 725 Heavy-Duty Wonder-Under.

Compare and choose
- Wonder-Under 805 vs Heavy-Duty 725: which do I need?
- 805 is the regular weight: it keeps quilting cottons soft and is the right choice for most quilt appliqué. 725 has a heavier adhesive layer for denim, canvas, wool and other thick or textured fabrics where regular web lets go. Use 805 unless the fabric is heavy, because 725 stiffens light fabrics. Pellon 725 Heavy-Duty Wonder-Under
- Wonder-Under vs Steam-A-Seam 2: what is the difference?
- Steam-A-Seam 2 is pressure-sensitive, so shapes stick in place and can be moved before the final press. Wonder-Under has no tack until it is ironed, which some quilters prefer because there is nothing to stick to the scissors, and the bolt is more economical. Choose Steam-A-Seam 2 for complex layered designs, Wonder-Under for everyday appliqué and volume work. Steam-A-Seam 2 18" x 3 yd
- Will Wonder-Under make my appliqué stiff?
- No more than any fusible web. Pellon states the fabric keeps a soft hand after fusing. To keep large shapes softer, many quilters cut the center out of the web and fuse only a ring around the edge.
- Which side goes against the fabric?
- The rough, webby side goes against the wrong side of the fabric; the smooth paper faces the iron. Trace your shape on the paper first, remembering it will come out reversed, then press, cut on the line, peel the paper and press the shape to the background.
- Can I sew through it by machine?
- Yes. It is 100% machine stitchable, so you can finish appliqué edges with a blanket, satin or straight stitch. Sewing through web is also how the pieces stay put through washing.
- How much is on a 17" x 10 yard bolt?
- Ten yards is 30 feet of 17" wide web, roughly ten times a typical 1-yard package. It stores flat on the bolt and keeps well as long as it stays dry and away from heat.
