There are 3 demos on YouTube showing how to use my new 10" Log Cabin Trim Tool Duo. I am really excited about this new tool. It is so versatile. Just open YouTube and type in creativegridsusa and you will go directly to the video demonstration that will show you how to make several variations on the basic 10" block using the one ruler. They are many demos for a variety of Creative Grids rulers on YouTube. You can also go to the Creative Grids USA facebook page to see more about the ruler and patterns.
