Welcome Sue from Central California. We all have our own version of the "Eureka quilt pattern" as we struggle with a particular function of quilting such as getting a quarter inch seam to be a quarter inch seam or as kindleaddict63 was working on her FMQ (free motion quilting) skills. We would all love to be able to go out a buy that skill and stop struggling to make it work. But that moment when it all comes together and we have found the sweet spot for that quilting challenge, we get the Eureka feeling. It's the feeling that all the struggle is behind us and we can move forward.
