Mandy, I have seen and responded so some of your posts, and I can see that you are serious and really fired up about this project! It is a big undertaking for anyone, so you go! ! !
One thing that helped me to add to what chico posted, is once I had the floor in and the walls cut, I mocked them up temporarily, and the held up cardboard where the cabinets would be to get a feel for where they would be. Doing this, I actually decided to move them back and up a little for some rollover, and maneuvering room, so it's nice to get a real feeling for it even thought it may throw you back in to designing land again, but hey that's what it's all about! The plans are just a guideline until you begin construction!
Hope to meet you in the middle of SC and TX someday!
