Topic: Rules for ordering adjectives correctly
Below is a link to a great article on adjective order in English.

Apparently, the correct order is:
Quantity or number
Quality or opinion
Size
Age
Shape
Color
Proper adjective (often nationality, other place of origin, or material)
Purpose or qualifier
If you get the above in the right order, no commas are required, except if you have two or more from the same category.
In other words, it's not correct to simply drop all commas between adjectives. Nor is it correct to use commas between all adjectives, which is what I've been doing.
There are numerous good examples in the article. Although most come naturally to native English speakers, not all cases are obvious.
Have fun!
