Showhome style blinds and cushions

[Chasingcars]

Loking around lately at lots of new houses and notice the showhomes always have really striking roman blinds with matching material for the cushions on bed or sofas. However most of the furniture stores I have looked at offer some striking cushions but dont have offer blinds to matchl, and vice versa. Does anyone know a highsteet shop or onlin retailer where i can get off the shelf blinds with matching cushions?
thanks
