I have never drafted a patchwork block before so I thought this would be a good challenge. I tried to find a pattern that was regular and repeated. I selected the flower and star pattern in this screen.
I have used a CAD mechanical program to draw the pattern. I find that the geometry deletes the flowers but it gives a good tessellation .
I drafted the pattern to fit a 6" square but this is quite a detailed block and at this size it could be sewn but would be better scaled up. Times 3 gives an 18" square, which looks a bit big so I have decided to make it 12" square.
