I tried repairing the leather on my last car using a kit from my local auto parts store and it was a total disaster~ and when it came off a few months later the small hole became a huuuuge ragged gap
The kit & instructions Jesse pointed out are completely different from the POS I tried, but considering how both a) new; and b) expensive your rig is... Please, do yourself a big favor and have it done professionally! It may sting the wallet now but that's nothing compared with trying to live with or worse, fix a botched job, and the sooner it's fixed the less chance it has of getting bigger.
