Hi Tony
I use Rauls Canvas in Costa Mesa. I have used him a few times in the past and he does really good work. Not the cheapest but also not on the high end either.
He uses high quality thread that is guaranteed for 10 yrs. which includes labor if it fails and he only uses the best in all matl. I highly recommend him. I have his business card at my office and will be happy to give you his # if you want to give him a call
