While I made a couple of patterns for my latest doll, I also made some extras that maybe someone will find useful . (I might do some more, it's so much fun :D)
It depends on what program you use. In Photoshop and other programs that support layers I'd suggest putting the pattern on a new layer and trying some blending modes. In MSPaint, I use this method: [link] (by adding the pattern instead of drawing stripes)
I hope this helps, let me know if it's not enough and I'll try to help
Excuse me, I'm making a video game and I would love if I would be able to use these lovely patterns in it. It might be profit, I'm not sure yet, but I would appreciate if you'd let me use them with credit to you. Is it okay?
