The larger Aqua & Navy block is essentially made the same way I put together the Red & Grey Block.
After cutting strips from the selected prints - an assortment of aqua, navy & some white prints for contrast - I joined these into groups of 3 strips sewn down the long edge:
... I then randomly cut each of these into 3 or 4 strips of different widths:
..and joined these together into mini 3x3 blocks:
Some of the mini blocks needed an extra row to increase their size so that I would end up with a block as big as I wanted, so that was added where needed...
...and then I joined these 'mini blocks' into one big block:And then squared it up (or 'rectangled' it up in this instance) to finish:
I also made a smaller rectangle aqua & navy block using some of the left over strips, as well as some longer pieces of the same fabrics:
