Pellon Lightweight Sew-in Interfacing 2-Pack — Ultra-Light Polyester for Blouses & Dresses

Pellon Lightweight Sew-in Interfacing (2) is a thin, sew-in polyester interfacing sold in a two-pack and designed to add subtle structure to light- and medium-weight garments without stiffening delicate fabrics.

This sew-in interfacing is intended for use with wovens and knits — think blouses, chambray shirts, lightweight linen garments, and soft jerseys. Because it’s ultra-lightweight and made from 100% polyester, it stabilises seams, collars, and facings while remaining breathable and unobtrusive. The product arrives white and requires no pre-shrinking, making it convenient for hobby sewists and professional stitchers who want consistent results with minimal prep.

How will this interfacing change the look and feel of my finished garments?

Pellon’s PLS36 adds gentle support so collars, cuffs, and facings keep their shape without creating noticeable bulk. It preserves the drape of light fabrics rather than stiffening them, so garments retain a soft hand and natural movement.

• Subtle structure for collars, plackets, and facings
• Maintains fabric drape on blouses and dresses
• Reduces puckering at seams on lightweight materials
• Trims closely to seams to avoid bulk

Which fabrics and sewing projects are best suited to this interfacing?

This interfacing is formulated for light to medium-weight fabrics such as challis, broadcloth, chambray, linen, and jersey. It’s a go-to choice for garments that need a bit of reinforcement but must stay soft and flexible.

• Ideal for blouses, lightweight shirts, and delicate dresses
• Works well with knit and woven fabrics
• Recommended where heat- or moisture-sensitive fabrics are involved
• Not intended for heavy coatings or very stiff tailoring

How do I apply Pellon PLS36 sew-in interfacing correctly?

Cut interfacing pieces following your pattern, pin to the wrong side of the fabric, and baste in place before sewing the garment. After stitching seams, trim the interfacing close to the seam allowance to minimize bulk and keep edges smooth.

• Cut interfacing to match pattern pieces — no pre-shrinking needed
• Pin and baste onto wrong side of fabric for accurate placement
• Sew garment as instructed, then trim interfacing close to stitching
• Use gentle machine wash and tumble low or dry clean per fabric care

Will this interfacing hold up in washing and everyday wear?

Pellon PLS36 is machine-washable and dryer-friendly when matched to garment care instructions, and it also accepts dry cleaning. Because it’s polyester, it’s dimensionally stable and won’t require special pre-treatment or pre-shrinking before use.

• Machine wash warm; tumble dry low or dry clean
• 100% polyester construction resists distortion
• No need to pre-shrink before cutting or sewing
• Two-pack supply for multiple projects or backups

Who is this for: Pellon Lightweight Sew-in Interfacing (2) suits home sewists, fashion students, and small-batch makers who work with delicate or midweight fabrics and want reliable, low-profile reinforcement. It’s especially useful when you need neat, soft finishes on collars, cuffs, facings, and seams without sacrificing fabric drape. Because the pack includes two pieces, it’s convenient for multi-piece garments or repeated alterations.
