Red Cabbage

I am late with my quilt (sorry Judy) as I did all the quilting on this arty farty  photograph of half  a red cabbage and was pleased with the finished result. I thought I had bottom line  thread in my bobbin but I found out it was washaway when I sprinkled the quilt with water before its final pressing. Arrgh!#*#

AND why is it called red cabbage when its clearly purple??
