This was a request, so this will be for just making this one kind of picture caption.

Step 1
Open up a new image in Photofiltre along with this brush.

Step 2
Open up the brush and copy it by pressing Ctrl-C. Then select any color to be the color for the lips.

Step 3
Now on the blank image, go to Edit >> Paste Special >> Mask.

Step 4
Click the sharpen button once.

Step 5
Now click the Text button and make your settings like mine. I used the same color I used for the brush for the text.

Step 6
Open up the text tool again.
