I heard on the radio this morning about the Depressed Cake Shop, a unique pop-up shop where every single cake on sale will be grey, colour only revealed on the inside. Set up to raise awareness of mental health issues; proceeds to mental health charities. Popping up in various cities, e.g. in London from 2 - 4 August 2013; there will also be one in Australia! Apparently some celebs have revealed how baking has been a therapy through which to channel their moods, etc. There is a Depressed Cake Group on Facebook but I'm not in tune with that technology!!
I think a PP cake shop would be a great idea. I love the thought of chatting to others with similar experiences over coffee and cake, coming out of the shadows and meeting together.
