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.
