Back in the day my old man use to take his limos, (back then people smoked in them) to a upholstery repair place an they used Vinyl powder an super glue, mixed them together to fill burn holes. Then they would have a tool with different patterns (about 1" round) he would wait a couple minutes after putting vinyl mix into patch area, then press to match pattern of vinyl. Then mix vinyl paint up to match color an airbrush to cover. Looked great but it didn't have the original flexibility, Alittle hard.
