I'm sorry Poppysmum. That picture is a "standard" on another forum I frequent and is meant as a, "Dude, where's my picture!?!" smiley, not one to be offensive. I forgot that not all forums are the same and what may be an accepted joke in one place might not be in another.
Upon re-looking at the smileys, I can certainly see how it could be taken the wrong way.
The pillowcases are adorable and I'm sure they'll be loved for years to come!
