I'm looking for some for a couple of woollen cardigans with holes that are too big to neatly darn. I really like the cardigans and don't want to chuck them out. I don't want shiny black or brown leather, what I'm looking for is something cloth or perhaps suede in a soft blue or green colour but I don't know if such a thing exists. I was looking at those "plasters for clothes" but they aren't big enough and I'm looking for something a bit more subtle. Any ideas (other than making my own!).
