Whatever works for you is the right way. If you like to chain stitch as I do, imagine this. Number your rows top to bottom. Alphabet your columns left to right. Sew Row 1, blocks A & B, then row 2, blocks A & B, etc. when you get to the bottom you can keep chain stitching by sewing Row 1, Blocks C & D, Row 2, Blocks C & D, etc. When you get all your blocks sewn into 2s, you go back and join 1A/B to 1C/D, then 2A/B to 2C/D, etc. Hope this makes sense.
