All of the methods mentioned in this thread require the aquisition of skill. Pour coating ain't as easy as it looks. And blade or well coating can be messy in the hands of someone like me, with the hand-eye coordination of a drunken earthworm. Its realy a matter of personal prefference. I like to pour coat, but cheat by edging the glass plate with a hydrophobic substance,wax.
I will say that, of all the methods I have tried, probably the easiest is the method Denise describes on The Light Farm.
