JustABeginner Report post Posted November 5, 2018 So, I know the book says DON'T burn on chrome treated leather, just veg tan. But I have some beautiful colored leather that I want to design on. So what kind of mask should I wear to protect myself? Thanks. Quote Share this post Link to post Share on other sites

Get a 3M vapor rated mask and you'll be fine, but ventilate the room too. Quote Share this post Link to post Share on other sites
