Yes, a thumbnail or informal sketch is the birth of any type of design. Without this important step, you could be wandering the design Sahara for months without any real direction. Thumbnails can be as intricate as you want them to be; a sketch on a dinner napkin (preferably paper) or a colorized pen sketch on good vellum – your choice, just do one. For any print, web or any design element, a thumbnail is a tentative plan of attack on any design project.
My one important train of thought…failing to plan is planning to fail. Going without a thumbnail means wasted time and money, none of which is a good thing to waste these days.
