I am making a Log Cabin for my son for Christmas. I used the Barn Rasing arrangement. I put 3 borders on mine. I am attaching a picture for you to see. I took the photo late at night so it is dark, but you can see the way the borders are done. The first border is the red from the center of the block, the second is the first light and the third border is a complementary green but one not used in the blocks.
I hope this helps. Ultimately, a quilt is your unique design and since it is yours it is never done "wrong".
