www.joggles.com is based on a river delta. The fabric is one I painted. I put experiments in a drawer and go through it when I need backgrounds for things. There always seems to be something that works, although this one was stiff and a bit hard to stitch through by hand.
The threads are Perle cotton and embroidery floss. The stitches are straight stitch, running stitch, chain stitch and Frence knots.
Thanks to everyone who comments. I wish I could get back to all of you, but the garden is producing and taking my time.
