You are not alone in your shopping habits. I found this cool FQ it's black with a pink skull and crossbones print on it or maybe it is just skulls. I'm going to it into potholders with the print on one side and a larger version of the skull and crossbones in pink to match appliqued on the other side with pink binding. I've had this FQ for over a year now.
I think a green or purple sashing would look great with those blocks depending on which color you want to focus on the most.
