Another demo post I've had in the hopper for a while!
I like the look of a checkerboard pattern, but it can be a little too tight for my liking...and also (truth now!) a lot of work, to brush slip on each individual square. For a checkerboard pattern that's a little more dynamic - and also easier to achieve - I sometimes use squares of cut newspaper.
I cut several layers of newspaper at once. I don't usually measure but cut squares (or "almost" squares) about 2" each side.
This works best on leatherhard ware. Here's how it looks on a platter:
I keep a little dish of water beside me as I work. Dip each square in the water, then drag it gently against he edge of the bowl to wipe off the excess. Arrange the paper squares in rows, corner-to-corner:
You could, of course, use any shape for your paper resist. With some care you can even do relatively delicate shapes. Torn paper makes for a nice dynamic line.
