First the shape of the bird. I always mark the contour lines and feather patterns.


They will be a guide for a successful bird even if you do it all in the same color with no regard for light or dark areas.
But if you opt for a bird of colors then
you must not only think of the colors but the values... See if you can define the lightest and darkest areas of this bird.

Then you need to gather your threads.. First pick the lightest and darkest shades and then several in between. These are the threads I pulled for the bluebirds. Together like this is is easy to see the change in value.
First I put the lightest color stitches in all the areas of lightness I identified. They are irregular and you think they won't show through but they will. I always satin stitch with a single strand...
Then I add the darkest color where it belongs.

color.
So if you put in your lights and darks and follow the contour lines with the between colors.. It works like magic....
The bluebirds are done on a very lightweight cotton handkerchief backed with fusible tricot interfacing... I also do birds (animals) on a tight weave muslin or on felt...both would also backed with fusible tricot interfacing... No matter what material I'm working on the VERY FIRST STEP is to stitch a very tight chain stitch all the way around....always, always , always.
It really defines the edges as I stitch into it as I progress and it makes it very easy to cut out.
If I have omitted something or am unclear, I need you to ask questions so I can get it all right...
