What is adjective order?

I have found two adjective orders OSASCOMB and DOSSACOMQ
OSASCOMB stands for:
Opinion Size Age Shape Colour Origin Material Purpose

and DOSSACOMQ:
Determiners – e.g. a, the, my, your, few,
Observations – e.g. interesting , entertaining, 
Size – e.g. small, 
Shape – e.g. round,
Age – e.g. new,
Color
Origin – e.g.American,
Material – e.g. silver,
Qualifier – limiters for compound nouns.

Native speakers usually "feel" the right order. If you are not a native speaker maybe you will be able to come up with some sentence in your language which will help you remember the proper order :)
