@aecasey Thanks April, I will have a try but not sure if I will get a chance as we don't put up our Christmas decorations until Christmas eve before we go to midnight mass as for me that is when decorations should go up. Therefore not sure I will have much to try it on.
and here's a tutorial on shaped bokeh if you want to give that a try: https://digital-photography-school.com/make-custom-bokeh-shapes/
Have fun!
