Final project ideas

Ideas for my final project are buzzing round my head with increasing frequency. Following on from my last project I have decided to stick with a 1970s vibe and hopefully create a print that is super adaptable to various interiors and homewares.
Hmmm.. How to achieve this though? My other niggling thought is that I need to develop a British theme that I am comfortable with that explores British quirkyness and eccentricities.
I need to look back at my childhood photos and talk with family to see what other themes pop into my head. What do you remember from the 1970s?
