Shopify is the e-commerce platform that I decided to use for selling my leather products on. It's very easy to act as administrator on it since it's a one stop shop for everything I need. I'll admit that the plug-ins are expensive but if you don't need too many plugins, it's a great platform to get started quickly.
The Shopify theme that powers this website is from OutOfTheSandBox and is called the Portland Turbo Theme. I love the incredible ease with how the theme works when customizing. It's very intuitive. They also have regular theme updates that you get for free perpetually once you've purchased. I will forever only use themes from OutOfTheSandBox.
The Doldokki Waterdrop Awl from FineLeatherWorking is used to make sure that each diamond stitch hole is the correct size and shape for the thread to sit in and have a nice angled look - often referred to as a European design.
The Doldokki Edge Beveler from FineLeatherWorking is used to remove a bit of leather from the edges to make the edges a little bit rounder and more finished. It thins the edge profile down a little bit as to reduce bulk.
The John James Needles appear to be the industry standard when it comes to stitching. I've only ever used these needles and only ever in two sizes, #4 (the ones I use now) and #2. They've been around since 1840 and have never snapped or failed on me.
This Regad Electric Creaser from FineLeatherWorking is used to add creases to the panels of your leather project. It is also use to heat edge paint so that it adheres to the leathers edge. With the many tips available, this is definitely a tool I use often.
I use these Linen Threads primarily in the Fine 632 size for all my leather products. This is a very popular linen thread that's used by a lot of other small batch leather crafters. You'll have to wax the thread first, so that it can easily go through eat of the stitch holes.
Chevre Chagrin is really soft goat leather that I use primarily as liners and interiors to a lot of my leather products. It comes in a variety of weights but I often choose to use 2/3oz or (0.8mm to 1.2mm). It's supple feature makes any leather product feel very finished and luxurious.
