The hanshita printout is perfect with all the detail intact. The needed tools are some rice paste or wall paper paste (anything that is removable later with water), and a sponge brush or, my preferred method, a sponge roller.
These rollers make quick work of the task of spreading a perfectly even layer of rice paste over the block. They come in all sizes!
There it is, a nice even light layer. I found the compromise between too much paste, which makes the tracing paper tough to remove later, and too little paste, which causes the tracing paper to peel off during carving. Sometimes it peels off before I am done carving details and I'm left to guess where the stem of the flower should be.
I just hand press the paper onto the block after aligning it carefully. I smooth it down evenly but not too much so as not to disturb the tracing paper.
The heavy backing paper is easily removed either while the rice paste is still a little wet or later after it has dried some. I have found no difference regardless of when the backing is removed.
