When you start a series of new work, think about how you are going to display the pieces so that they lay flat when hung.
Think about the wisdom of making long thin pieces, for the same reason as given above.
Decide on a uniform way of depicting the birds: soft and dreamy or strong and precise, not both.
Know that there are different shades of grey, and that you have enough of the one you begin with, to finish all. Plus choose the quick and easy computerised stitch that you have used in the past and not the free motion stitch that takes an age to complete, resulting in boredom, resulting in not finishing!
Perhaps if I had thought about these things back in October when I began these, they would have been finished a lot sooner!
Not to worry, a lot was learnt and fun was had!
