Love how it came out!!!
On the left and right, you can add 'half' hexes of your border fabric. Just cut 3 triangles (you might have to unsew the seams on the ones that 'stick out'. The top and bottom are more problematic (well, for me) I just cut off the excess and continued with the border fabric. If you do this, remember to leave the 1/4" past the seam.
