I have three rules for good quiltmaking. They are:
1. Accurate measuring and/or marking.
2. Accurate cutting
3. Accurate piecing.
All the rest is up to the quiltmaker. Mary Ellen Hopkins (a quilter of world reknown) said it this way (or something like this).........and called it "one's personal seam".
After the above three then it becomes personal to the quiltmaker in how the rest comes together.
Quiltmaking has evolved a 1000 times or more since the 1970's with the introduction of new technology, tools and methods. We have to adapt these new ways to our own personal style and desires.
