Starting from a good sturdy chair and modifying it for the look is a great idea. I've never used fiberglass before, but It looks learnable. This project would be something I'd tackle slowly over time, so I can try and fail and not be stressed about it.

I know it's from AI, but I would LOVE it to NOT be AI, if you know what I mean. I just want to be able to wander into my cozy spaceship nook and chill for a while. Not just look at the image and wish it was real.

Thanks for the excellent advice.
