I wanted to sharpen my planes and chisels to a fine edge without the expense of a series of sharpening stones.  Plate glass is expensive but marble or granite tiles are just as flat and very reasonably priced.  With a 12″ x 12″ marble tile as a base, I stack the various grits of wet-dry sandpaper on top.  Each layer is taped at the top only.  I put the finest (1200) on the bottom and then courser layers on top until I get to 200 grit.  To use it, mount the chisel or plane blade in the honing guide.  Spritz a little water on the 200 and draw the blade toward you.  When the scratches are uniform, progress through the finer grits.  Touching up between major sharpening means you start with finer grits.  When not in use, dry the sheets and set the tile with sandpaper on the shelf.
