Of that's a relief! I was honestly quite worried that I'd screwed up somehow! Thank you so much!!
Also thanks for the advice @tsunkasapa. @Dwight, @Hags and @Silverd! Really appreciate the input! I should have clarified that I only just used water to clean/"deglaze" it cause I read elsewhere on here that deglazer is generally unnecessary unless there's a particular issue (oily hands or similar). But I am curious as to the reasons behind your suggestion to pre-oil for non-black dyes? This may seem like a silly question, but I thought the whole point of needing to deglaze leather before dying is so as to remove the oils in there to get a better spread of the dye?
Cheers to you as well @Garyak! I only just got into leatherwork so I've been trying to not go overboard buying things yet, haha.. But I have looked into airbrushes a bit already cause it's been recommended to me a few times now Fingers crossed I'll be able to afford it... One day, haha
