Less Picking more Choosing- almost there

I have my 25 large blocks (10 1/2") sewn and several sewn into rows.
Question IS-- Do I set them 5 x 5 and add a black border and some applique OR.....


Set them on point with black setting triangles and do a little applique?


Either way I am leaning towards a black border of some kind. I can see me doing a vine with flowers or butterflies (or both!)
