I just saw this video on Facebook and am passing it on. It is a really nifty way of cutting tumbling blocks if you don’t like the hassle of Y-seams.
Here is the link: https://www.youtube.com/watch?v=XkxfvMVnZV4.
The video was posted by TeresaDownUnder but Teresa states that the original technique is attributed to Rebecca McCreary and also to Marci Baker, so it is not a new idea.
Amazing what you can find on YouTube.
Happy stitching.
