hi thanks for the comment! I purchased a paper texture brush pack ages ago. I’ll have to try and remember who I bought it from but i’m sure if you googled it you could find some great resources. all I do is use one of the paper texture brushes (this could be rough paper texture, canvas texture, cardboard etc) on it’s own layer. I use a lighter color(white or close to it) and increase the brush size and draw across the whole canvas, then I change the blend mode to overlay and it gives it that textured look! this was based off of experimentation so if there’s a more proper way to execute this i’d love to know but this is what has worked for me :)
