It is an image of a piece of rock art.
This is the piece of fabric I received.
I have decided to take the criss cross pattern on the legs as my quilting design and have marked it by hand with a bone marker not being too fussy as to wether the lines were straight and even as I thought that this would reflect the original image better. I purchased a variegated thread to do the quilting with.Details of thread and more pictures to follow.
