A missed challenge

Those of you who follow my blog (and thank you so much for doing so!) will notice that I sometimes go missing in action (these times usually coincide with a mountain of marking - I teach Biology to Uni students, and I often get buried under hundreds and hundreds of prac reports, exams and assignments).  During these times, I still keep up with looking at blogs and challenges, and some of the challenges I store away for a future cardmaking session. 
This card fits in with a recent CASual Fridays challenge that I missed - it was called Black & White plus One - that is, make a card with black and white, but add one more colour.  I went with a red piece of flocked acetate from the recently released Stampin' Up catalogue.
