For this I picked out the spiral which I drew in one of the earlier exercises. I did both machine stitching as well as hand stitching. For the machine part I played a bit with different stitches and I have to say I really like the zig-zag effect I got on some of them. Next to that I also practised some hand stitching using different threads and yarns.
The fabric I used for these samples was a P&B cotton.
