As any good novice should, research what we're going to make.

Materials, tools, techniques, design, and processes are all important things we should consider - what is the purpose of your bag? What's it made of?

What did I need?I needed a backpack for uni that could fit a 15" laptop, as well as some A4 booklets sideways.

I highly recommend watching guides on YouTube - the Leather Build Along #4: Messenger Bag by the talented Mr. Ian Atkinson proved hugely useful in both the design and the construction process of my bag.

Design

When designing a bag from scratch, it is often easier to use another suitable bag as a rough template for the dimensions of the bag, and the length of the straps.

Additionally, I kept the pieces as whole as possible to minimise seams and stitches as they would be very time-consuming being done by hand, as well as being more durable. To do this, incorporate bends and creases of a whole rather than separate pieces for the edges. This method will tend to produce a more rounded figure as opposed to sharp angles. However, if angles are your thing and you have some time on your hands, go right ahead.

Feel free to download my template and use, or personalise it to suit your needs. But please do give due credits if you share it elsewhere.

Compile a list of required tools & materials

Before purchasing the materials, look at tutorials and images of similar bags online.

This will be very useful in catching anything you might have missed.

When you're sure the list is good, buy them!

I bought my items online, but it's a good idea to shop around for best prices. Check your local tanneries, craft stores, or even your leather-savvy friend.
