So I saw a bit of the leather on my driver’s door armrest start to crack. There are two splits. One is the size of a finger nail. The other smaller. No idea how that could’ve happened but I figure it’s from the heat and the car is seven years old. Any suggestions on how to DIY fix it or patch it? Basically I don’t want it to spread anymore. Is it even worth getting a professional to fix it or would that be too much money? Thank you!

This picture is too large but it’s the first time I’ve uploaded. Let me know if there’s a way to shrink it. Thanks
