I love it. This is the method Judy Mathieson uses in her books, and it is how I made my first two Mariner's Compass blocks and my first feathered star. I do think it is a great technique and I once made a list of what I consider the advantages because I received so many questions about it. But on the disadvantage side, I have felt that as I have been working in miniature, it is not quite as precise as just working with a regular paper foundation. So on my tiny quilts I am back to tearing off papers. Been doing it today, as a matter of fact. *Heavy Sigh* : )
Thanks for the video link Leeanne. It was very interesting and a great new technique to try.
