Sally, Many of the things I've learned are from Bonnie Hunter's mystery quilts.....how to measure for borders correctly so as not to have ruffled borders....getting those points more precise and how to use the various tools. While making this years mystery quilt I was so very thankful to one of you who suggested cutting the wing units for clue #6 a bit longer so that they came together perfect! I'm not an expert quilter and still struggle with choosing colors, knowing how their value will work together in the end result. This is such a wonderful group of talented quilters who share their wisdom so willingly.
