I am guessing that the backing is actually the same shade of pink as the pattern that is on the front that has the same black ... uh ... what are they?
On the front, I saw the cat pieces and thought, 'Oh! those must be cat tails"
however, now that I have seen the back ... well, they don't exactly look like catepillars ... hmmm...
sweet mystery of life! Just think! Could it be a message of some kind?
