Looks like you're doing an Adult Eye Spy!
Consider any of the patterns that allow for focus fabrics and just change the focus fabric each time to tell your husband's story! there's a lot of star patterns that would work well for this ... his fabric in the square centre and then coordinating points around.
And of course, many others with simple squared centres, then sashing and cornerstones.
Also, the hexagon eye spy design, with the star points.
Or of course, you could stick with the simplistic patchwork jumble of an eye spy!
Of course, the possibilities can go on and on!
Some will work better with your fabrics you have ... some not so good.
So many variables depending on how well your fabrics coordinate or not.
Good Luck!
