Sea Turtles - Part 1

My next project is going to be another reverse applique wall hanging, this time with sea turtles as the theme.  I'm still working on the actual reverse applique design and hope to have that finalized shortly.  I have also been working on putting together the sea turtles layer.  This is the one that lays underneath the top layer and gets exposed when the reverse applique design is cut out.  Here is what this layer is going to look like, I still have to finish sewing together all the columns.

The top layer is going to be lighter in colour and these are the fabrics that will make up that layer. The plan for this layer is to do more free form curved piecing to try and give the look of waves on the ocean. The blue in the upper right hand corner appears to be rather dark in the photo but in relation to the fabrics in the turtle layer it is a fair bit lighter.  The lighting in my sewing room is great for sewing since I have lots of windows and natural light, but I guess my camera things other wise.
