Figured out what the turkey work is supposed to be for the wren. This is what the feather looks like:
Instead of doing turkey work - which I can't do well, especially that close to other stitches - I used wool, frayed it, and used a dab of JE glue at the back. I don't know if there's anything special about this glue; since it is used for JE it must be ok. Then I have to pick out all the black fuzz that ended up on the fabric. The male wren is done.
Starting on the female wren.
