Harlequin.

Fig 1. 

Researching further into market levels I found Harlequin who create high end flamboyant wallpaper designs.
Using a range of specialist finishes such as metallics and a range of different textures they are a specialist in statement wallpapers.
They create a diverse range of designs in a large range of styles, suiting to various different room styles.
I think their styles of papers are really interesting with lots of mark marking and expressive designs, which I think my work would lend itself well to.
Harlequin are also a design team, and are the sort of company that I could see myself working within, and I definitely would like to aim for the higher end of the market purely because of the elaborate designs and the more extravagant details.
