Thank you all for your advice. I have learned several things here.
1. Know what size quilt you intend to make before you cut.
2. Know the cutting instructions of the pattern you intend to use in order to make best usage of yardage. Some patterns call for cutting border strips "length-of-fabric" first, before cutting other strips the width of fabric.
3. It is "OK" to cut large lengths of yardage down to workable lengths. 3 yards is long enough for a king size quilt!
4. After getting the fabric on the straight of grain with salvege to salvage, I think I will pin every half yard through the salveges to keep it from shifting as I go to the next yard and the next. I might even pin at the fold line also.
Then I can fold the whole piece in half lengthwise bringing the fold line up to the salveges. From there, I can fold accordian style as Petthefabric suggested.
Again, thank you all for your suggestions. Very insightful for me.
