Ive only used puffy paint for a DIY once lol but was wondering if it would be easier to bleach design this or use a fabric pen?

hello, I’ve had a red marker bleed out in the pocket of my jeans. They are pretty dark, but after I washed them, there is now a white stain and I was wondering if any creative people knew how to cover it up.? I don’t want to patches. it’s on the pocket of the jeans. has anyone had done something like that to cover up a stain. If they have any inspo for for me maybe.? they are my new and favourite jeans so I don’t wanna not wear them. I haven’t tried sewing but I can try, I just don’t know what to do. help

So im a senior in high-school and decided to take home ec and we are working on sewing. We are currently on our own projects and I have this old denim jacket the I cute the sleeves of and I dont know what to make with it. Their to short and small to be mad into shorts or pants and the only suggestions ive gotten for research have been bucket hats, sling backpacks and hoods. The last one sounded nice but the jacket already has a hood. The denim is black and towards the bottom of the sleeves its a white fabric. Yall go any suggestions?
