The Sedron is a great backpack for teenagers and adults alike and was designed by Adam, as he wanted a rustic and hardwearing design. It’s a unisex design but it’s an ideal bag to make for the men if your life as we so often struggle to find bag patterns suited to men.

It’s sized to fit a standard paper binder and a medium size laptop. Instructions are included for an interior bottle pocket, exterior and interior zip pockets and a laptop strap. The bag doesn’t include padding for a laptop, but the strap is designed to hold a laptop that’s within a protective sleeve. The bag also features a small grab handle that’s built into the straps. This grab handle is designed to fit 2 or 3 fingers and is suitable for grabbing the bag, but not designed for hanging or holding it.

We’ve rated it as intermediate. It’s a massive bag, which takes some time to construct.

Due to the size, we recommend using waxed canvas (12oz/400gsm) for the exterior fabric and heavyweight (18oz/600gsm) waterproof canvas for the lining. Using these materials means you won’t need to interface anything and will only need a small amount of stabiliser. This keeps the cost down and also saves you time. You’ll need to have some bag making experience to create this bag.

The main stabiliser is for the base and the back panel. For this you can use Peltex 71, Decovil Heavy or foam. We use a new method that means you won’t need to fuse or sew in the stabiliser. There’s also some foam in the pattern, which is used for padding the shoulders.

This is a PDF digital sewing pattern in English available for instant download. See the “DOWNLOAD INSTRUCTIONS” page for details on how to download your pattern after purchase.

This pattern is written using both imperial (inches) and metric (centimeteres) measurements.

Included in the photos are bags made by our pattern testers. Please be aware that some of the testers have made small modifications to their bags. Instructions for these modifications are not included in the pattern.
