Step 3 Lay down a dingbat with floating and anti-alias checked. Save to the alpha channel as Top. Step 5 Promote the floating selection to a new layer called Top. Turn off the visibility of this layer. Step 6 Go back to the Base layer and load the Top selection.
Flood fill the selection with a color.
Step 7 Duplicate this layer and call it Working. Turn off visibility of this new layer. Step 8 Go back to the Base layer and use the magic wand to select the area outside of the dingbat. I used a feather of 1 and a tolerance of 0. Step 9 Clear this selection.
