I took a class once on FMQ and machine quilting. If you are doing only SID, start at the top in the middle, SID down. Turn quilt around, start row next to one you just did, SID that row in opposite direction, and keep alternating from center to the right, or in other words advance to next row to your right until all rows from center to right are done. Then start again with row next to your very first row you have SID, turn quilt around so you go center to right again, row by row.
If you want to do an all over FMQ, say feathers for example, then first stitch down your rows with water soluble thread, then FMQ your feathers all over. Once washed your water soluble thread is gone. I did a queen size Drunkard's Path on my Viking Diamond Deluxe once. Puckers in the rows disappear after the wash. Feathers were the only quilting.
