here, though it would show up more as the thread is a much higher contrast. (scroll to the bottom of that post to see it) and how to do it is here. I think longarmers call them pebbles, mine are more like fine gravel. Though it is possibly a mistake, not in the effect but these little grains take time, loads and loads of it.
If you click on the photo you will see where I've drawn the feather on the fabric and how I've sewn completely elsewhere. I often do this as when I'm sewing I can see a better way to get nice curves. So why do I draw it all out only to ignore it? Well it gives me a frame work which I may or may not use but I can see the angle of the curves I've drawn and then make the final decision in thread.
The marks shall wash out and the threads will be buried and I'll be a very happy quilter.
I can't believe it has taken me over two years to go back to this format. It's about 12 or 15 inches by 60". I have thought of entering it into the Festival of Quilts though I think their new size restrictions might not allow for this shape. I will have to take a look at the entry forms.
And the quilt that started it all.
