I had already decided that my block should feature the grey fabrics but I did need to add just the one blue to represent the water around the fort as much as to recognize who it was firing on the fort. The suggestion to make those strips from the corner red did not sit well for my plan so I used the grey stripe. My fort sits surrounded by water.
I wondered how this block would look if turned on point as that is a potential for how I might set the blocks so here's a second look:
By the way, if you left click on the photos you can see them in more detail and for instance see the grey stripe fabric I speak of.
Are you following along with the flickr site? Some people are doing amazing things with their blocks like the quilter today who printed the photo of the Charleston ladies on the rooftops watching the assault on the Fort. Oh my goodness.
