Apparently it’s called the Royal Order of Adjectives, and it’s essentially: determiner, opinion, size, shape, age, colour, origin, material, qualifier.

You don’t have to use all of those in the description, but that’s broadly the order to use them in to make it sound ‘right’. So for example in the comment I made above, it fits because I used:

• determiner (The)
• size (big)
• age (old)
• colour (red)
• material (wooden)

in that order. I’m sure I was never taught that in any organized way (I just had to look up what it was called lol) but I still got it in the right order anyway just by typing it out in the way that felt right, which I think is interesting.
