FastFuse Woven Interfacing

Sold by the 0.5 metre. Add your desired quantity in the box, e.g. for 2.5 metres enter 2.5.

When considering price, don't forget it's 67% wider than most interfacings.

FastFuse is 120gsm, woven fusible interfacing. It's thick, with a soft touch on one side, and a strong glue adhesive on the other. It is thicker than G700 or SF101 interfacing. The interfacing is cream coloured, rather than being bleached white as most interfacing is. FastFuse will strengthen your cotton fabric, stop edges from fraying, and reduce stretching. Your fabric will still look, feel and move like fabric but it will feel more substantial. Ideal for bag making.

Fusing Instructions
To ensure a good bond, follow these instructions.

  1. Place the coated (shiny) side of the interfacing on the wrong side of your fabric.
  2. Iron section by section for 3-4 seconds, using a medium heat with no steam.
  3. After fusing, lay the pieces on a flat surface to cool. This allows the glue to bond securely.
If you get any glue on your iron, you can easily rub it off using a scrap piece of fabric.

Block Fusing
This is our preferred method for interfacing.

  1. Calculate the amount of fabric needed for your project and cut it out in one large piece.
  2. Cut a matching piece of interfacing and fuse it to the fabric in one go.
  3. Once the interfacing has bonded, cut your pattern pieces out.
This method means you only cut once and you’re less likely to get glue on your iron.

Some photos include hardware or finished bags for illustrative purposes but this listing is for interfacing only.

While we do our best to cut accurately, it is cut by hand, and none of us are perfect. There may be a difference in length up to 5%. For example, if you order 50cm, the length may be between 47.25cm and 52.5cm.

For cuts over 3 metres, we can't guarantee a continuous cut as the interfacing may contain flaws that need to be cut around, but we will do our best. Interfacing and fabric may contain small flaws. We will do our best to ensure your cut is flawless, but we will allow the following flaws:

  • Flaws within 10cm (4") of the edge of the fabric
  • Anything smaller than a 5p coin (18mm or 3/4")

Interfacing with flaws outside of these parameters will not be sold under this listing. If your interfacing contains flaws within these parameters, we will usually include extra to make up for the inconvenience.

Or you can send us a Whatsapp message +447518142548. This is your “right of withdrawal”. Items must be returned at your expense, within 30 days of receipt for a full refund. We recommend that you obtain proof of postage or tracking when returning your items as we can’t guarantee receipt of your order.

To complete your return, we require a receipt or proof of purchase. The simplest way to provide this is to reply to the original order confirmation email. To qualify for a refund, your products must be returned unused and in a re-saleable condition. Once we’ve inspected the returned items, we’ll refund you within 14 days. The refund will be processed to the same payment source used for purchase. In certain circumstances, we will only grant a partial refund. This includes where any item is not in its original condition, is damaged or missing parts for reasons not due to our error, or any item that is returned more than 30 days after delivery. 

When you cancel or return your order, we incur costs that are not refunded to us such as payment processing fees and postage costs. As a small business, these costs negatively impact us so please check measurements and read product details thoroughly before purchasing. If you have any questions before ordering, feel free to send us an email.

If you haven’t received a refund when expected, we recommend contacting your bank or credit card provider. Please bear in mind, it can take several days for your bank to process the refund and show it in your account.

If you think you’ve received an item that’s damaged, faulty, or otherwise incorrect, please contact us straight away by emailing us at with a photo and description of the fault. We will get back to you within 48 hours to resolve the issue (usually quicker). 

If we’ve sent you the wrong item, we’ll let you keep it at no cost, and we'll also send you the correct item. 

If you believe an item is missing, please check the packaging thoroughly and unpack your entire order. We like to do our bit to help the planet and that means reducing packaging and space. To achieve this, we often roll items within each other. For example, if you’ve ordered 2 x 1 metre cuts of zip tape and 1 metre of webbing, we’ll roll them together in one bag. If your order is completely unpacked and you’re certain an item is missing, please email us at
