Jan, that was a great tutorial. It was very nice of you to share it with us. I just finished my first quilt with triangles - square-in-square, setting triangles, and border with QST's. Wish I'd had your 'go-by'!
What is the difference between a square-in-square and a snowball? Do you put the seamline inside the square in the snowball? How much?
Thanks
Sue
