Everything I do, I draw out my idea(s) first as a sketch. I am old school and just freehand draw. I have an Architectural Design background, but I also did some machine drawing in school. I like to noodle out what I am thinking and maybe do a perspective. Then I pass it along to someone who is knowledgeable in that field of expertise. Some of the below I have done, done after altering past the sketch, or scrapped the idea. I post this just to maybe spark some ideas, and "what if" in someone. I need to scan a bunch more onto my laptop and post them here. What if?... is a method of thought for me.
