I found it!
I’ve found the name of that lovely shop I wrote about here! It’s called The Collection. Their website introduces a whole new way of viewing and experiencing Wall Art aka wall paper. Its founder, Alison Grant showcases various known and up-and-coming artists in such fields as photography, textiles and lighting. What I’ve viewed on her site just makes me even more excited about decorating my new home in the City of Lights! Nine days and counting, folks!
