After tearing the strips, ironing and very lightly starching, I got them sewn on last night. They are very nice strips, nice and straight, and it only took a few moments to tear each one. What a time and aggravation saver. I realized one advantage that if the pattern is printed well, tearing it makes the edges follow the repeat at the same point all along the length. That could really come in handy, especially if you are matching pattern on a mitered corner.
I think I would use this for piecing backing too. That's also a mental block of mine, worrying about cutting them straight.
