You start with the basic spread:
3: Near Future
Remember past is within the last three months or so, sometimes in the last six. Present is what's up with you/the querrent right now and within the last couple days. Future I labelled near future so as not to confuse you about the final future card. This near future is short time, in about three months, sometimes as late as six months, but not usually.
Then you had above and below the present:
4: Consciously know/feel
5: Unconsciously know/feel
Sometimes where our conscious selves are can be radically different from our subconscious selves, and seeing that in the cards can be seriously helpful in figuring out what's up.
Then sideways over the present:
6: The cross you must bear/the crux of what haunts you about the question, as in what is really gettin' your goat about this?
Now to the right, you make a straight vertical line, and bottom up:
7: Your persona, as in what you are projecting forward to other people and yourself
8: Your environment, particularly the people around you.
9: Your hopes and fears, what you want to happen and what you are afraid of. Since the cards have both negative and positive aspects you can usually use one card, and what is present the most, the positive or negative is what is ruling you more, your hope or your fear.
10: Future (about 1 year), what's the probability outcome on this path?
Optional, you can separate hopes and fears. Sometimes this is helpful in getting a little more clarity on the dynamics between the two.
If the final card is a bit worrisome pulling out a clarification card or two can be beneficial. This is particularly helpful as action cards or things to keep in mind cards, so that you will have a better outcome or weather the storm more. Sometimes you need to do a whole 'nother reading though to get more specific clarity on how to change an ill fortune for the better.

And Now The Sample!
The Querent asked "How to move forward with my writing?"
With that in mind, how would you interpret this spread?
What's holding her back?
How is she not being true to herself?
What are the relationships do you see between the cards?
Note: This querent admitted that she reluctantly sees herself as the Queen of Wands
Also note that I chose to use the optional Fear card separately as a sort of clarifier for the fear aspect.
Up close! Including cards that are covered in each section!
Also, to clarify, this is how I personally use the Celtic Cross. It is what makes the most sense to me. There are other ways people perceive it and those are valid. You do what works best for YOU.
