Bigger than I thought it would be. It looks better in person than pictures...
Sorry I didn't take good before pictures.
I bought one patch for one of my seat that had a lot of shredding. There was a lot left over so I used it for the other side too. (I'll probably buy another full patch for the other side eventually)
Its not a professional repair, but it'll do. In the past I've considered having my seat professionally repaired but didn't want to spend the money... this makes me satisfied, for now at least.
Side note, if you see a tiny tear in your leather seat, buy this now and fix it... it'll get worse so fast!
