Pinterest for me has been one of the biggest and most important tools I’ve been using over the last year.
It is fantastic for cataloguing different visuals from all of the digital outlets I use and with the iPhone App I have it at my fingertips as long I can get a signal. It allows me to put together a decent mood/inspiration board effortlessly because most things on trend I’ve archived somewhere.
For interiors this is my current board: https://www.pinterest.com/davidbulldesign/new-apartment-interior/
I also keep a board for the items in the pictures so I know their names and where I can buy them, funds permitting
