Bag Making Supplies

Constructing a functional bag requires three key categories of supplies: webbing/strapping, closure fasteners, and adjustment hardware. For the handles and shoulder straps, a heavy-duty polypropylene or cotton webbing is essential to bear weight. For closures, you will need secure fastenings such as magnetic bag clasps, gold tuck locks, or press studs. Finally, to make your straps functional, you will need adjustable sliders, metal D-rings, and swivel clips so the straps can adjust, pivot, and detach cleanly.

When shopping for strap hardware (like our 20mm, 25mm, or 38mm bum bag clips, D-rings, and strap adjusters), the millimeter measurement refers strictly to the internal width of the slot where the strap feeds through. To ensure your straps look professional and do not bunch up or slip during use, always match the width of your webbing tape exactly to the measurement of your hardware. For example, our 38mm black heavy-duty polypropylene webbing should be paired exclusively with 38mm bag sliders and clips.

The choice between these two closures depends on your bag’s style and security needs. Magnetic bag clasps are discrete, low-profile fasteners consisting of two interlocking metal discs that snap shut automatically. They are the ideal choice for shopping totes, internal pocket flaps, and elegant evening clutches. Conversely, a gold tuck lock buckle is a highly visible, mechanical metal lock. It requires the wearer to press a spring release to open, making it a highly secure, structural statement piece perfect for satchels, messenger bags, and backpacks.

These two components are secret weapons for giving handmade bags a high-end, retail-quality finish. 15mm silver bag feet (studs) are inserted through the base of structured bags to lift the fabric slightly off the ground, shielding your beautiful exterior material from dirt, moisture, and friction. Meanwhile, sewing cotton piping cord (such as our Size 3 or Size 6) into the exterior seams of your bag stabilizes the fabric, helping the bag maintain its structural shape and three-dimensional profile even when empty.
