I used my Kaffe Wall Grid for a week-long workshop with Kaffe Fassett and Brandon Mobly. It worked great for our final project. I would recommend watching a YouTube video on how to use it effectively, especially how to roll it up correctly, if you have to transport your project. Roll it carefully from the bottom! Also I recommend preserving a row of your pattern, (vertical, horizontal, or diagonal) just in case things shift. It's a great tool for planning your quilt design.
