I'm not sure if this counts as a spread as it is quite flexible. It works with the Angels and Fairies decks, should work with others as well as long as the two decks seem to you to fit with each other.
Shuffle the Angels deck, then the Fairies deck. Lay out the Angels deck in any short spread such as:
1. Situation 2. Obstacle or challenge 3. What will help you over the obstacle
Then lay out the cards from the Fairies deck just below or overlapping the Angels cards. The Angel cards seem to state a general theme and then the Fairies will support them by being more specific or by suggesting a frame of mind for you to adopt.
