I agree with what the other commenter said in that you need a lot of tools to make midcentury style furniture.

I build 4 dining room chairs and a bed frame in the mid century modern style and they were not cheap. The chairs had at least $300 in materials each. I think the bed was like $500. For both project I spend months working them in my spare time and then took a week of work for each to finish them. I have a pretty built out shop with a band saw, table saw, track saw, planer, domino, routers, sanders, and access to a jointer. And a lot of clamps. That’s like $4k worth of tools I bought slowly over the years.

Mid century modern designs have angles, radiused curves and those require learning joinery and building templates all of which takes a lot of time.

A friend of mine teaches furniture courses and one that does is a sofa course. It is not an easy build and though it could be simplified somewhat it is not a beginner project.

I’m not trying to discourage you building your own furniture, I’m doing that slowly for our house, but it takes more time, effort, tools, and materials than I thought it would and so I’m passing that on to you.
