I would start by not looking at the whole quilt (can be overwhelming).Start by selecting blocks to make a cohesive 4 patch (example - put 4 blocks together in such a away as to have the dark bits or the whites meet in the center). You may end up with 18 big blocks or maybe just 12 - doesn't matter. Then use a sashing that will stop the eye - either the dark blue or white, not a medium color. Depending on how many blocks you end up with, border it to make the size you want. If you only use 12 blocks, you can sew the remaining together and then cut them in strips (think a modified piano border) and use them to make it bigger, with a small border between the top and the border. I have found by separating and doing a bit of changing, I have turned a top from something I didn't want to work on into something I really liked. Good luck - I'm sure they will like it.
