Thistle Leaves

Today I have been adding a bit of machine stitched detail to thistle leaves.  One of the panels on the Diamond Jubilee quilt is of a thistle, representing Scotland. 

Looking at the leaves again, now that it is a few weeks since I completed the blanket stitch, the centres seemed empty, so the machine stitched veins in the middle were today's job.  I didn't bother with a stencil.  I drew the central veins on the back with fabric marker, so the bobbin thread shows on the front.
