I have a leather couch that is only 3+ years old and has now started to develop small tears around the seams in one of the cushions. Here is an image of the tears:

I think it would be best to try and fix the issue now to prevent the tears for worsening but given their small sizes, it seems that it might be hard to do something like a patch. I've seen kits like this one on Amazon which seem to be appropriate for this situation. Would using this kind of leather repair kit be the best option to handle this case or is there a more suitable alternative.
