This is a photo of a quilt with the freezer paper drawing of the feather I want to use with the shiny side pressed to the wrong side of the fabric. The light you can see in the lower right hand corner is from a light placed on the floor below my glass sewing table.
I was disappointed I couldn't get a photo of how clearly the feather shows through the fabric for me to be able to draw straight over the lines showing through.
I did a post some time ago on how to find your perfect marking pen here.
Once you have traced your feather or any other quilting motif, just peel the freezer paper off the back and iron it down where you need the same feather or motif repeated. You can normally get away with using the same piece of freezer paper about four times.
