Moving right along, the wing is stitched in Milanese Stitch using alternate rows of solid color and overdyed floss.
The second tail feather is stitched in Mosaic Stitches with Smyrna Crosses using DMC floss and Planet Earth silk
Feather number three is a Victorian Step Variation stitched horizontally. The "white" areas are actually overdyed floss, but the color variation doesn't show up too well in the photo. The colored lines are irregularly spaced, but it is easy to get the correct spacing because the stitches are painted on the canvas.
