1. trim away all selvedges, square up ends by tearing to get straight
2. place two lengths RS to RS and seam both sides after pinning to keep even
3. snip the center of ONE pc and rip lengthwise... this keeps the back from getting out of square and produces the large center, 2 small sides that gets away from the center seam which is mostly eye appeal...visually, the human eye prefers odd numbers...
