each color sequence has 16 sections of color (4 repeats of each shade of blue).

i used the planned pooling calculator to come up with a design that i liked based on my stitch counts.

this was made in all sc.

the border (soft navy) is 2 rounds in hdc.

i made a big zig zag across the back border. start with a new piece on the edge in the back, slip stitch through 2 strands of a stitch, ch2, bring down and over and slip stitch through two strands on another row, ch2, bring back up and over and continue to the end.
