Depending on the types of stores in your area, you may find most of the required materials from hardware stores, specialty stores, and big-box home stores.
Amazon is a great place online to find items you can't find locally.
When you make a purchase on Wood Shop Essentials, watch your inbox, you'll get a link to my resources page, where I link directly to the same materials and hardware I use in my projects.
I know how frustrating it can be to follow plans that don't provide links. It leaves you searching sometimes for hours online for the right parts.
That's why I always post the exact materials I use so you can easily find them, and buy the same ones, or at least get an idea of exactly what it is I use, so you can find them locally if that's what you prefer.
