Hi, I wanna give bleaching a hoodie a go tomorrow for the first time. I was planning to sketch out my design with chalk then bleaching the white spaces in this image however I know a lot of it is super intricate. I was wondering if anyone had any tips for getting fine details and if anyone had any insight on how much the bleach bleeds when painting. Thank you!

Sorry if this is a dumb question, I'm new to bleaching shirts. I want to bleach a shirt with the QOTSA tuning fork as the main feature, and was curious if there is a specific type of material I should use to get a red or white color, or if that only depends on the bleach, or both if that makes sense?

Also, what can I use to make outlines? Can I just use a regular white pencil?
