Description
Sure Fuse Medium Cotton Woven Fusible Interfacing 125gsm
Sure Fuse Medium is a 100% cotton woven fusible interfacing designed to add support, body and structure to your sewing projects while still maintaining a softer flexible feel.
It works beautifully with quilting cotton, cotton canvas, bag linings and many other sewing fabrics, making it a popular choice for bag making and structured sewing projects.
At 125gsm, Sure Fuse Medium is heavier than G700 and SF101 interfacing, making it ideal when you want additional support and stability without creating an overly stiff finished result.
The gallery images shared in this listing show examples of how Sure Fuse Medium looks when fused to quilting fabrics and the structure it can achieve in finished bag making projects.
Perfect for Bag Making Projects
Sure Fuse Medium is lovely to work with when making:
- Handbags and totes
- Crossbody bags
- Bag linings
- Zipper pouches
- Wallets and purses
- Structured quilting cotton bags
- Home décor sewing projects
Because it is woven, it handles and presses more naturally than many non-woven interfacings while still adding the support and body needed for beautifully structured bags.
How to Apply Sure Fuse Woven Fusible Interfacing
Sure Fuse Medium is easy to apply and creates a strong bond when pressed correctly.
As a professional bag maker, this is the same interfacing I personally use in many of my own projects.
Using a Heat Press
I recommend using a cotton heat setting (approximately 180°C) and pressing for around 15 seconds.
Using an Iron
Use a cotton heat setting and press each section for approximately 15 seconds to allow the adhesive to properly bond to the fabric.
TIP: Press and hold the iron in place rather than moving it around like traditional ironing.
Pressing means lifting the iron, placing it onto the section being fused, holding it in place for approximately 15 seconds, then lifting and moving to the next section.
Important Testing Recommendation
Always do a test press using a scrap piece of the fabric or material you plan to use before applying interfacing to your final project.
This allows you to test the heat and pressing time to achieve the best possible results for your chosen fabric.
Applying to Vinyl Faux Leather and Specialty Fabrics
When applying interfacing to vinyl faux leather, leather or specialty fabrics, place the material with the wrong side facing up and position the interfacing adhesive side down on top.
This allows the heat source to be closest to the interfacing adhesive, helping it fuse more effectively and evenly.
Sure Fuse Medium vs Sure Fuse Firm
Choosing between Sure Fuse Medium and Sure Fuse Firm depends on the type of structure you want your finished project to have.
Best for projects where you want:
- A softer more flexible feel
- Everyday bags and accessories
- Reduced bulk
- Beautiful structure while still maintaining movement
Best for projects where you want:
- Extra body and stability
- More structured bag shapes
- Firmer bag panels and bases
- A more structured finished result



















Smooth, nice mid weight without being bulky
I hadn’t used this before and gave it a try. It is very good and gives just the right amount of firmness.
Exactly as described perfect
Great when making slouchy style bags.
