Some concepts and ideas only need an introduction and a small amount of information that present the minimum basics, with links for further info in case the reader is interested in more. And some are made greater when the reader truly understands their purpose, and that sometimes, requires some explanation, and therefore space. And we know that plenty of space is available with a 4-fold brochure.
A 4-fold brochure is plenty of work, and as we like to take it a step at a time, this PSD mockup shared by Mr. Mockup features only one side, leaving room for additions and remarks for the other one. So designers can, in a matter of seconds, insert their designs from promotional ads and mini-catalogs to awareness flyers and campaign designs thanks to the smart object layers, and create a pattern with the different colors that can be added to each paper/side as well as the background.
