this is my first tutorial ever

I call it double process and as the name sounds it is pretty easy.
Sometimes we want to use a mix of water and other blocks, but the water block dissappear
so we can easily fix that by adding the water block again. So we will have same water block on same x,y,z positions twice.

the final version, all places are cover by water...

As you can see this technique is very easy and can be used also on dirt and grass based block.
Have fun
