In English, as you know, the adjectives always come before the noun and, when there are more than one, this is the most common order:
When the adjectives are of a different category, we DO NOT use a comma:
- A new steel steak knife.
- That big red plastic bag.
When the adjectives are of the same category, we DO use a comma:
- A distinguished, friendly, beautiful woman.
- Two beautiful, soft, comfortable cushions.
If you can join the adjectives with AND or BUT, then use comma. If not, do not use it.
