I knitted this in 2 panels, DBJ, seamed together.

After adjusting the image to get a satisfactory two-color version, I divided the image in half - sort of. I needed to have 1 stitch overlapping in the middle for the seaming method described in DBJ Swatching & Seaming.

I wanted to have a 6-stitch solid border around the image, so I reduced the image to 12 fewer stitches and rows than I would finally use, then added that back in, after the adjustments were to my liking. Total width was 393 stitches, which I divided into 197 and 197. when I split the image I overlapped by one stitch.

I decided I preferred the look of dark water and a lighter shade for the land. This makes it a bit of a brain bender, because now color 1 (white in the image) is dark, and color 2 (black in the image) is light. For the sake of being able to follow along, I inverted the image to look more like the finished piece, but then I also had to invert the way the machine selects needles, which is done in DBJ by selecting the KHC button, as well as the KRC button!

The next thing to keep an eagle eye on is that only one yarn gets picked up when switching colors at the color changer. I caught both yarns once, before it started knitting -- phew!!

Knitting the first 1/2 of the left panel took 3 hours of knitting, that does not include the approximately 45 minutes I spent ripping back 6 rows after I got the order of colors off! That was tracks 1-5.

By the time I got to track 8, I was able to knock out a track (68 rows at this width in just over 15 minutes - as long as no disasters occurred.

Aaaaand the disasters showed up nearly at the end. After loading the final of 11 tracks, I neglected to press BOTH the KRC AND KHC buttons. I was knitting row 12 by the time I felt there was something wrong. The colors were reversed. It took about 2 hours to painstakingly unravel those 24 rows of knitting, but I managed it. Starting over at the beginning of that track I was knitting row
4 (8 passes) before I could see that the fabric was bunching up between the beds. A sure sign, and yup! somehow and additional ribber needle had gotten into work. This meant that the same group of every other stitches on the ribber were knitting with every pass, and the remaining needles had not knitted at all, for 8 passes. Unpicking that mess was much trickier with the extreme load on some stitches, and very little on others. Several stitches dropped, but I managed to retrieve them!

After that, the remainder of knitting on the second panel went smoothly. When knitting the circular rounds of red waste yarn at the top, and given my experience on the previous panel of that yarn not knitting off after a few rows, I brought all needles out to hold before knitting each row. That worked swimmingly.

Next step: mattress stitch those 712 together, block and attach the backing.
