My problem with binings is that it NEVER seems flat, or even. Despite reading books and articles, and watching tutorials on YouTube, nothing I do seems to look rigt. I measure athe the top, middle and bottom od all four side, and try to get the most accurate number, but no luck. I have tried straight grain and bias binding, and every quilt I have ever tried ti bind myself, has lumps, bumps, and puckers. Forget mitering, my corners are all rounded, not a neat, sharp, crisp corner. I finally gave up, and started paying my LA'er to put the binding on. This seems to be my biggest problem - no problems at all with piecing, borders, or even backing, but my bindings are hopeless.
