Juliana Christmann and Moritz Büsselberg shared an awesome editorial design project featuring magazine spreads very well designed using a classic grid system. I mentioned before and I will keep saying it, this type of work for me is what inspires me the most.
Arthur Petrillo shared an awesome project focused to help the design community in London. What the Hackney is an independent zine made by East London artists to promote artistic expressions in the neighbourhood.
A New Type of Imprint VOL. 8 is an editorial design project by Anti. For me the best thing about editorial design projects like that is that they gives a lot of ideas and references about typography, grid system and especially white space.
99U Quarterly Magazine releases issue 4 and it's safe to say that is one of the most inspirational editorial pieces out there. Very heavy in typography, keeping the consistency in colors, making and breaking the grid.
