Wonderful idea - thanks. It would be great for classes.Archival-quality card sleeves are also good for making your own reading boards - get a large piece of foamboard, lay the sleeves out in your preferred pattern (e.g. 9x4, 8x4+4), paste or tape the sleeves to the board, and insert the cards you draw for readings in those sleeves for longterm viewing and rumination. I use double-sided tape to attach the card sleeves to my board.
I cut some foam board to fit my preferred layout and covered with felt, marking the houses with a fabric pen. I layout cards for the Grand Tableaux on it. The felt makes it easy to pick up cards from the board and it keeps them from sliding around much. I can leave the cards out and move the board from my table to bed to wherever.
