i had to lengthen my porch roof by about an inch. kept not gettin the 2nd story on straight. i think because my seams were a little scant. so the house was a little wider than it was suppose to be. and i remembered something someone else had said, add extra on the sides to make it a 12 inch block, so i just was adding the extra to the orginal pieces. and we all can embellish after we get them done. right?????
