>>2457115that's totally an option anon. i'm just starting to learn how to do it myself, making your own backpack and gear is truly the endgame its just a massive time investment to learn.
unironically reddit /r/MYOG and ultralighter forums like backpackinglight are the best even if the end goal of what you're making isn't ultralight. it seems like that's the only crowd of people who care enough to make their own shit. just search "MYOG" which means "Make Your Own Gear" and you'll find shit online.
also i forgot the url but you'll find it eventually i'm sure. there's a website that's sort of like a marketplace for templates, which you can buy and then modify to your liking. i suggest starting with easy shit like fanny packs and water bottle holders when learning templating, its hard. the sewing part is easy.
you also have to kind of sperg about materials science but thats no big deal.
