Be careful, woodworking is a deep rabbit hole to jump down. It can be a wickedly expensive interest, but if you’re patient and put in the work you can find some cheap or even free tools and materials. But I don’t think I have to lecture anyone about GAS here.
Paul Sellers blog and youtube channel is an amazing resource for beginners, especially if you plan on working with hand tools. youtube in general is filled with great resources for new woodworkers.
Finding a lumber supplier can be tough. Good hardwoods from a lumberyard are expensive. Reclaimed lumber can be super cheap, but it will take a lot of prep to get it workable. Menard’s has the best lumber selection out of all the big big stores near me. I use their “select grade” pine for 50% of my projects. It’s straight, stable, and surfaced on four sides so you can start working with it right away.
I’m currently gluing up the top for a sitting workbench. I’ve been using my dad’s garage to work for so long, now this is the start of my own space and I’m super excited about it. Later today I’ll plane the edges and practice the mortise and tenon I’m going to use for the legs.
