The Celtic Cross is the basic spread, in my opinion. I think it's not as last Thursday as one could think, especially for the ones who are newbies in Tarot. I've got my favourites, but the CC goes beyond that.

Oh Pirbid
I like your usage of the word 'demodé'; it is how I feel about the Celtic Cross, but I am coming into terms with the spread after some readings and finding the placements that to me make the most sense. In fact, the one that came with the Rider Waite deck makes the most sense for me as far as the Celtic Cross placements/position meanings go.

the above mini spread is interesting. I have seen different versions of it too

I could read them almost from the start but at that time I also had a close related who would pointed out some facts when I didn't understand. I got overwhelmed by the accurate information, I also remember... I would have a lot of vital messages coming through those tarots - and this then established my friendship with the tarot world once and for all.
I think it's important to go with the feeling of the cards that you DO understand. The cards that you do NOT understand cand be left aside for a while until you get the grip of them. You should try not to feel any stress or feel pressed about getting to know them well, the great knowledgement will probably come after many years anyway... Another thing which is important is reading, reading and again reading, so that you will discover and memorize again and again... Good luck!
