I used a dark green thread to do a continuos line drawing of leaf veins. You will note I left an open channel in which I will later add darker shadows.
I had considered leaving things as shown previous but was drawn to add further richness within the leaves by using a pinkish burgundy red to fill the vein channel.
I like the end result. I hope you do too. Click on photos for detail view.
Next... to get the quilt blocked.
