This video is a long one, but it will take you step by step through a variety of tools and techniques that will help you created the exciting layered look so unique to laser cutting. These are the same techniques I use when creating any illustrations in Adobe Illustrator and will work for creating layered paper/vinyl designs if you're using a vinyl cutter as well. Let me know if you have any questions as I may do a part II video if there are things I missed.
