That's just one of the wonderful things about quilting, Margarita! There are so many different ways to accomplish everything, that everyone should be able to find something that works for them. This was my first paper-piecing project, and I learned so much!!
The most important lesson I learned, I think, is that careful measuring and precise trimming are critical to everything fitting together well in this kind of project. It's not hard to do, but it's a step that a lot of us tend to skip. We just need to get into the mindset before we even begin that we are going to take our time to do this right, and it's going to work! Sue and I will both offer pointers along the way, and I hope that anyone else out there with suggestions and/or ideas will jump right in to help!
