Sure Fuse is a premium cotton woven fusible interfacing designed to add support, body and structure to your sewing projects while maintaining a natural fabric feel.

Created with bag makers in mind, Sure Fuse provides the stability needed for beautifully structured bags without excessive stiffness or bulk.

Whether you’re making handbags, totes, crossbody bags, wallets or pouches, Sure Fuse helps create bags that hold their shape while still feeling beautiful in everyday use.

Why Bag Makers Love Sure Fuse

As a professional bag maker, Sure Fuse is one of my favourite interfacings because of the balance it provides between structure, flexibility and ease of sewing.

Unlike many non-woven products, the woven construction allows the interfacing to move naturally with the fabric while still adding the support needed for bag making projects.

Sure Fuse is also heavier than G700 and SF101 interfacing, making it a popular choice when additional support and durability are required.

Many customers who try Sure Fuse quickly discover it becomes one of the most frequently used interfacings in their sewing room.

Understanding the Sure Fuse Range

The Sure Fuse range has been designed to make choosing the right interfacing simple.

Sure Fuse Medium 125gsm

Perfect when you want:

• Beautiful everyday structure
• A softer, more flexible feel
• Support without excessive stiffness
• Bag linings and bag exteriors
• General bag making projects

Sure Fuse Firm 150gsm

Perfect when you want:

• Extra body and stability
• More structured bag shapes
• Firmer bag panels and bag bases
• Additional support in bag exteriors
• A crisper finished result

Many bag makers use both products together, often choosing Medium for bag linings and Firm for bag exteriors to achieve the perfect balance of structure and flexibility.

Available by the Metre and in Value Saving Packs

The Sure Fuse range is available in multiple purchasing options to suit different styles of sewing and bag making.

• Sure Fuse Medium 125gsm by the metre
• Sure Fuse Medium 125gsm 3 metre pack
• Sure Fuse Firm 150gsm by the metre
• Sure Fuse Firm 150gsm 3 metre pack

The convenient 3 metre packs are ideal for customers who regularly use Sure Fuse and would like the convenience of a continuous pre-cut length while also saving compared to purchasing individual metres.

Application Tips

Sure Fuse is easy to apply using either a heat press or household iron.

For best results, use a cotton heat setting and press each section for approximately 15 seconds.

Always press and hold rather than moving the iron across the fabric.

When working with vinyl faux leather, leather or specialty fabrics, place the interfacing adhesive side down against the wrong side of the material so the heat source is closest to the adhesive layer.

As with all fusible products, testing on a scrap piece before applying to your final project is always recommended.
