Need help Stitch in the Ditch on this quilt....What pattern do I travel?

[coffeebreak]

I have this quilt all ready to SITD..however...I need advise on how to do it to this design. I know "how" to SITD, but with all the squares and triangles and "ditches"....what is the best way to do it on this design? I know about the part of doing one row down, and the next row up so as to keep the fabric in line and all that, and start from inside and work way outward. But...that is how I did the center design, and have to many thread ends, starts, stops.

If I start at the top of the quilt and sew down the main row sides...then go side to side...okay, but then I have to do the inside ditches where the squares and tri's are and that can bunch. But if I start from the inside I still have all the stops/starts threads. Frankly, my thread matches so exactly (first time for everything!) and my walking foot does so well, I can hardly tell where I have stitched when looking on the front! I want to ahve as few thread ends as possible, but can't figure a pattern to travel to get each ditch!

So...anyone have suggestions or advise on how to Stitch in the Ditch this quilt? I have included a pic of the full quilt and a close up of the squares/tri's block. I also plan to Stipple in the large brown squares between the 5 stripes...so if you have any suggestions on that I'd appreciate it too. And maybe stipple the center square on each block.
