đŸȘĄ Golden Rose Guide to Interfacing

What is Interfacing and Why Use It?


Interfacing is a woven, non‑woven, or knit fabric that adds:


  • Body, shape, and structure to garments

  • Reinforcement to high‑stress areas (buttonholes, waistbands, plackets)

  • Support for maintaining a silhouette while worn


It’s applied to the wrong side of pattern pieces before sewing so it becomes an extra layer.


Commonly interfaced pieces include:

  • Collars, cuffs, facings

  • Waistbands, pocket flaps

  • Plackets, zipper areas


Types of Interfacing


By Construction

Type

Structure

Grainline

Best For

Notes

Woven

Like woven fabric

Yes

Medium/heavy fabrics, delicate wovens (silk)

Cut on grain; stable, durable

Non‑woven

Bonded fibres

No

Bags, accessories, craft projects

Cut any direction; less durable after washing

Knit

Looped structure

Yes (stretch direction)

Knits, stretch wovens

Moves with fabric; prevents over‑stretch

By Application


  • Fusible – Glue dots on wrong side; adheres with heat/steam.

    Pros: Quick, clean finish.

    Cons: Not for heat‑sensitive fabrics; test first.


  • Sew‑in – Basted to fabric; no heat required.

    Best for: Loose weaves, textured, or heat‑sensitive fabrics.


  • Fabric as interfacing – Use cotton, batiste, muslin, organza, flannel, horsehair canvas (tailoring), or lightweight knit/mesh.


  • Specialty – Water‑soluble strips for temporary stabilising (e.g., hems, seams during construction).


Choosing the Right Interfacing


Match weight to fabric:


  • Similar or lighter weight than your fabric

  • Slightly less drape than fabric for subtle structure


Examples:


  • Lightweight rayon shirt → lightweight, flexible interfacing

  • Jacket → medium‑weight interfacing for structure

  • Knit jersey → lightweight knit interfacing

  • Ponte/double knit → medium‑weight knit interfacing


Golden Rose Rule: When in doubt, go lighter — too heavy can make areas stiff and unbalanced.


Working with Interfacing — Tips & Best Practice


Before You Start


  • Pre‑wash fabric and any sew‑in interfacing fabric (e.g., cotton, muslin)

  • Test fuse on a scrap to check adhesion, shrinkage, and drape

  • Check grainline/stretch direction for woven and knit interfacings


Cutting


  • Follow pattern’s cutting layout for grainline

  • For fusible: cut with glue side down to avoid sticking to shears

  • Trim seam allowances to reduce bulk


Applying Fusible


  • Use a press cloth to protect iron and fabric

  • Press, don’t iron — lift and hold for 8–12 seconds with steam

  • Let cool completely before moving to set glue

  • Re‑mark notches and pattern markings after fusing


Applying Sew‑in


  • Baste within seam allowance

  • Treat as one layer with main fabric during construction

Colour & Finish Choices


  • Black for dark fabrics, white for light fabrics

  • Sheer fusibles for lightweight or semi‑transparent fabrics

  • Avoid visible shadowing on light fabrics by testing first



Troubleshooting

Issue

Cause

Fix

Bubbling

Too much steam/movement before cooling

Press, don’t iron; let cool flat

Poor adhesion

Wrong heat setting or dirty iron

Clean iron; increase heat/steam per instructions

Stiff result

Interfacing too heavy

Switch to lighter weight

Fabric distortion

Ironing motion or stretch during fusing

Use lift‑and‑press method

✹ Final Golden Rose Tip


Interfacing is like the hidden architecture of your garment — invisible from the outside, but essential for strength, shape, and polish. Choose it with the same care you choose your fabric, and your finished piece will look and feel beautifully made.


We stock a wide range of interfacing here at the Golden Rose shop. Pop in for some advice on which interfacing to use.


We recommend Vlieseline products. Take a look at their product brochure: Vlieseline_GesamtbroschĂŒre_2025_148x210_44s_EN_print_Layout 1
