You need to go back to your client to find out what design era they want you to focus on for the design work. You are going to do this in the form of visual mood boards, so your client can SEE what the design eras that you are suggesting look like.
You will work in pairs or small groups to create the mood boards and each pair / group will focus on a different design era so your client will see images from all of them on offer.
Here are some Mood Board Examples
As you can see, they are all very VISUAL
In your pairs, make sure you collect a wide range of things from your design era
As well as including things like colours, textures, scenery, lettering styles ....
Give a good feel about what the design era looks like.
Pacific / Maori
Industrial revolution / steampunk
Art Deco
Japanese
Don't worry if the design era that you get to make a mood board for is not the one you are most interested in.
