There were two choices for the shape of the velour stickers: either cut out the perfect circle and then live with the consequences of misplacing them - or cutout the circle after applying a bigger square. I went for the latter, which worked out ok! I'm going over every corner of the PCB with a black marker anyways, to keep the appearance as black as possible. The velour is great for absorbing the light shining on it.
I found some molds on Aliexpress that seem to fit well with the soot sprites in shape and size, so I will not make my own molds for this. With every run I get around 25 weirdly shaped LEDs, which is nice. I even have a leftover mold in form of stormtrooper ice cubes now.
