The Pellon 805 Wonder-Under — 17" x 10 Yards White Bolt is the most widely used paper-backed fusible web for fabric appliqué. Wonder-Under allows you to trace designs directly onto the paper backing, fuse to the wrong side of fabric, cut out the shape precisely, peel the paper, and iron the appliqué piece directly onto the background fabric — creating a perfectly clean, precise appliqué bond in one simple process.

Frequently Asked Questions
- What is Wonder-Under used for in quilting?
- Wonder-Under is the standard fusible web for machine appliqué. Trace your design onto the paper side, fuse to the wrong side of the appliqué fabric with an iron, cut out the design on the traced line, peel the paper backing, and fuse the appliqué to your quilt background. The fused appliqué can then be stitched around the edge by machine or hand for a permanent bond.
- How does Wonder-Under differ from Steam-A-Seam 2?
- Wonder-Under requires ironing to fuse permanently and does not have a repositionable adhesive. Steam-A-Seam 2 has a pressure-sensitive adhesive that holds the appliqué temporarily before final fusing, making repositioning easier. Wonder-Under is the lower-cost standard choice; Steam-A-Seam 2 is the premium choice for complex appliqué layouts where multiple repositioning moves are needed.
- Does Wonder-Under need to be stitched over or is fusing permanent?
- The fused bond is permanent for typical use, but for quilts that will be washed repeatedly, stitching around the appliqué edge (satin stitch, blanket stitch, or straight stitch) significantly improves durability. The fused bond alone may eventually lift with heavy washing.
- Can Wonder-Under be traced through with a light box?
- Yes — the paper backing is translucent enough to trace designs from a light box, allowing you to reverse designs accurately for fusible appliqué templates.
- What iron temperature is recommended?
- Medium-high heat (cotton/linen setting) without steam is standard for Wonder-Under. Always test on a fabric scrap first. Some delicate fabrics may require lower heat with a pressing cloth.
