This is a short design video by Tonia Brooks showing how to create a line pattern that can be used for checker board backgrounds as she demonstrated in the latest iQ Academy class. This will be a very useful little pattern not only for background fills, but also to use in sashing, or to fill any square space.
This is the link to the video on Youtube. (I was unable to embed the video here.)
