Helen Godden is a teacher in Australia that I have learned a lot from in her online classes. She is also makes learning fun! This is one of her techniques to make quilting simpler, and it a brilliant tool when working on a quilt. Enjoy!
Helen's Panda marking pencil she sells on her website is a great tool, but shipping from Australia might be expensive if you live in the US. Another brand is the Ultimate Marking Pencil you can find at www.FullLineStencil.com in California.
To continue with the Roadmap technique, here is another video by Helen that shows some other stitches.
