On Quilt in a Day, E. Burns uses the 20 mile per hour rule-if you drive by at 20mph and it looks good, it is good. I was kind of bummed about my Tennessee Waltz quilt-things not matching up and i saw the show on tv where E. Burns made one and she was showing examples of the pattern. Guess what? they were not all matched up either. i thought if she could show them on tv, then i could be happy with mine.
