To do this technique, I did the following steps.
Step 1. I took a 4 x 4 piece of white card stock and stamped the image of the bat
with White Craft (SU) ink and dried with a heating tool.
Step 2. I inked my brayer with London Fog (Memento) ink and covered the
whole piece with it going up and down and across sideways being
sure to get it evenly covered with the grey ink.
Step 3. Wipe the excess ink off the bats with a paper towel.
Step 4. Stamp the bat image in Basic Black (SU) ink slightly offset
from the ghost bat images, using a Stamp-a-ma-jig for placement.
