30 days has September

This is the third month of my 30 day challenge. Again it will be on the pale green damask table napkin as the other two. So for September I am stitching stones, pebbles on to the white silk squares as the other two. Appliqué , needle turned. I have to speak to my quilt buddies to get enough greys. I want the pebbles in grey as that will echo the sketch colour of the 30 days in April and the black running stitch of June.
