Drawing the simplest shapes seems to be the hardest thing

I have a very simple, favourite cuff bracelet.  As I am trying to draw more often, that cuff was a subject earlier this week.  Very difficult, but the attempt at lower left does seem to be getting towards the shape ( drawn on top of an upturned plate to ry to get some sense of scale in to the drawing).  Tartan covers out for Burns night this weekend.

I used the "skew correction " function on my camera to try to straighten out this image, and it really distorted the cuff.  Interesting.
