The videos that I create here assume a basic working knowledge of Sketchup.
If you are brand new to Sketchup, I suggest that you use these two great rescources to get that basic knowledge out of the way...
Google has put together a nice series of videos for the beginner, to the expert.

Also, my friends over at www.go-2-School.com put together wonderful videos on a variety of topics. I have embedded two here that I think apply really well to Sketchup in kitchen design.
These guys do videos on a variety of topics, and they also do online, and live training classes, check out their website!
