sleeping cat bowl

So Marcia - trying to work backwards here on your resist technique, can you confirm or otherwise -

Glazed (yellow), black slip banded, shellac used to paint frames and cats, wiped back to reveal - ah, now there's a problem, How do you wipe back and reveal the yellow, without washing off the yellow?

I'm not good at thinking backwards,mnegative space etc. so am intrigued as to the order of things here.

apply the slip to greenware then the shellac and resist process. Bisque and glaze then fire. Slip comes through the glaze.
