Vinyl Patches?

so my headliner and seats are covered in rips and tears from 40 years of use.since my seats are patched with black ducktape, my big concern is the headliner. replacing it would be roughly 1k....not in my budget.

so does anyone know where they might sell patches(sew on? iron on? w/e-on haha) i just wanna patch up my headliner so it dnt get any worse, since it wont be replaced for another year or 2 prolly.

thanks!
