I was playing Stardew Valley and I had a cat shirt. Or so I though.
It was in fact a skull shirt. But I didn’t know that. I thought, “I am going to draw a giant cat head”. So here’s my new design:
At first, I drew it like so:
I painted it with white color only — those dark grey areas are just white pixels with very low opacity. But, as I know, those pixels would not be printed at all. There’s no point submitting a design with too many transparent pixels. That’s why I changed contrast, so only the white pixels with high opacity are left.
