One of the underrated values of oil paint is that with a small amount of experience you can make it handle like basically any other type of paint. Not only is this helpful in terms of things like storage space, cost of materials and overall waste, but it also reduces decision fatigue before you start your artwork - you don't have to decide what type of paint you need to use, you're just going to use oil paint
Here's where I'd start if I had to start from scratch:
Basic pallet in Bob Ross paints (ie red blue yellow white or cyan magenta yellow black white)
Turpentine
Wood panels (eg plywood, MDF) which I'd apply 3x hide glue layer for sizing and 6x gesso layer on top of that before painting
Brushes (I still struggle with picking brushes)
A few jars
A well ventilated space away from other people where I can just sort of leave it all and know it'll be ok
@nuala ah thank you. Space I can just leave will be difficult...
@Katharina I wouldn't say it's essential but I think it makes a big difference if you can find it. Or if not, even if you can find somewhere you're able to dump all your oil painting stuff and you'll know it will go undisturbed, like a big plastic box under your bed or a corner in your shed or something.
@nuala ah I have an art drawer where my things go in.
Clearly seeing in my minds eye that workspace and artists tools, just as you describe them.
