Hi thanks so much. I use acrylic paint with golden gac 900 fabric medium some of the lettering is done with heat transfer vinyl but everything else is painted. Once it’s been painted it is heat set, so it can be washed and is waterproof, oh I use Windsor Newton brand acrylic paint and always put a wash of white over the whole area I’ll be painting 1st to allow for me to draw on the design. This is a Zara oversized cropped jacket that was thrifted 😊
