In English, adjectives appear before the nouns they modify in a particular order:

Article or other determiner (a, an, the, most, four)

Evaluation or Judgment (horrible, special, attractive)
Size (big, tiny)
Shape (round, oblong, star-shaped)
Age (young, middle-aged)
Color (silver, blue)
Nationality (Polish, Mexican)
Religion (Catholic, Jewish)
Material (wood, steel, silk)

Noun

For example:

The big, star-shaped, silver ornament topped the tree.

A young Polish girl sent me this card.

Four big round cookies are in the blue silk bag.

TIP: It is more effective to use no more than two or three adjectives when describing a noun.
