2. Invert your selection (Select>Inverse or Shift+Ctrl+I) and activate Quick Mask Mode (click or just press Q on your keyboard). You'll notice that the selection is rough around the edges and doesn't match up exactly to the edges of your intended subject.

3. Reset foreground and background colors back to the black and white defaults (click the little or just press D on your keyboard). Painting on the red mask with white will now erase the mask. Painting outside the red masked area with black will add red masking to unmasked areas.

4. You can toggle between black and white by clicking on the bent arrow (shown) or by pressing the X key.

5. Paint and erase along selection edges carefully until edges of red mask selection are properly placed on all areas. I use a soft edged brush so that my selection has feathered edges to avoid that "cutout" look when I'm finished.

6. Exit quick mask, invert your selection (Shift+Ctrl+I), and save your selection by clicking on Select > Save Selection.
