spend anytime around me at all and i guarantee, we will have a conversation about the death of creative thought.
many of my hours are spent as a designer. at work, at home, at play, its what i do. so its stands to reason that i spend time thinking about design. a lot of time. and the best way to get any (preferably all) of these ideas down is to sketch them. a sketchbook is of primary importance to me. at any given time, i have one at work, one at home and one available within arms reach. though any paper i can scribble on will do in a pinch. it then simply gets stapled into my current sketchbook for later use.
having said all this, there is a growing number of those in the creative field that reject the notion of sketching. they simply turn on a computer and output ideas from there.
anyway, i have long maintained that this is not a good trend, and honestly, i hope its not a growing trend, but, if i have to relent at some level (and i won't), could those who refuse to use paper, maybe take a look at odosketch? it won't replace paper, but at least its imperfect and allows for exploration. and its kind of cool to play around in.
