Differences between the words for "decoration"?


While making a list of Christmas vocabulary, I've noticed there are several
words for "decoration". 飾り, デコレーション, 飾り付け, and 装飾 are the ones I've seen.

Judging by google images (with "クリスマス" added), they're something like this -

飾り - any kind of decoration  
飾り付け - arrangements or stuff on walls/hanging from ceilings, like banners and
garlands  
デコレーション - Not sure about this one...it seems like it's mostly for a bunch of
decorations together, rather than individual ones. Also, the decorations on
cakes  
装飾 - Decorations in public places

So, what's the difference between these? And are there any other common words
that mean "decoration"?




飾り=decoration

デコレーション=decoration

飾り付け=decoration or decorating, **the act of decorating**

装飾=decoration

They means the same thing, except 飾り付け may emphasize the act of decorating in
some contexts.
