A couple days ago, I was on a mission to find sturdy black construction paper to attempt to make bokeh filters to use on our Christmas tree. Very much in the holiday spirit, I tried cutting out the word JOY for my filter, which resulted in the picture below. If the lights were spread out a bit more, I think it would've looked great. Nonetheless, it was a really exciting process to see the way the lights shine through the filter.
Wishing you all a happy & warm holiday season with your loved ones.
