I am still having problems with stretching and puckering and need to really concentrate on that. Very noticeable on the top right part of wing. As it is still not mounted I may get away with it with putting backing between the work and the frame. Really enjoyed this technique again.
Update: I pinned and stretched on a board and managed to flatten most of the puckers down to just creases and it is now mounted. The picture is now of the finished and mounted work.
