I heavily used Pinterest when I was getting married nearly 10 years ago, just for images of how I wanted flowers to look, dresses etc etc. Since then I have stopped using it, because like anything else that becomes too big, it started to become flooded with, to my mind, complete rubbish.
I now use Instagram, in fact I got most of my interior design ideas for my new home from there. The difference between that and Pinterest is that it’s very easy to find out where certain items are from on Instagram, wallpapers, tiles etc etc but with Pinterest it’s nigh on impossible to do so.
