I started watching the tut, but disagree with them measuring the end of the quilt before putting borders on. What if the ends are wider than the middle? YOu would then have a wonkly quilt. Measure through the middle of the quilt across & up/down. I have always sewn my borders together before attaching on my quilt, specially when I make mitered corners, and I do 95% of the time. So anyway I didn't continue watching the tut.
