The best quilting tips and techniques often come from our "Ah-Ha" moments -- those immediate insights into a task. Maybe yours came when you discovered the best uses for fabric's lengthwise grain vs. its somewhat stretchy crosswise grain. Or when you first recognized that color temperature affects the perception of "light" and "dark" in a big way. Perhaps it was the discovery of a special way to align patches to sew a perfect quarter-inch seam. Or maybe it occurred when something didn't quite turn out as it should, and you knew exactly why.
