I love your art! How do you make such beautiful drawings with only "a few" pixels? Makes me want to try and make some cross-stitch embroidery with similar designs :)
It's been a while since I made this, but if I recall I put Ernst Haeckel illustrations into Photoshop, heavily boosted the contrast, and then moved those into ruin's bitsy image conversion tool.
I'm glad you enjoyed it! I hope you follow that inspiration and make some lovely embroidery.
