If these are the only fabrics you are using, I would go with the second set. The first set, the black blends together to much and you loose the design of the block. I think the large print fabric would make a wonderful boarder to pull everything together as stated above. I like the contrast in the second set of blocks but the one with the large print is off a little. I think if you could find a smaller print but still in the dark color it would work much better. I am inclined to lean to another black color, but then I always lean to black on everything. Try picking out a darker color from the large print fabric and see how that would work in the 4 patch and leave the large print for the boarder. Just a thought. Good luck in your choices.
