If you're looking for a good leather product makers and tailor, I would recommend the following:
Shop Name - Puma Exclusive Leather and Tailor
Assistant's Name - Jacky
Address - JI. Kuta Theater No.11, Kuta, Bali
Phone - (0361) 766990, 728216
Mobile - 081 747 27583
Email - jackyleather@yahoo.com
I had a leather jacket made for me while I was there - 940,000 Rapah (A$120) - not bad for the detail that was in it. I took an old vinyl jacket that I had with me so they could use it as a pattern. It is helpful if you can do this. They do not cut it up so you can have it back after they finish.
They usually as for a small deposit once you have agreed a price and the item is ready for pick up in two days' time.
Make sure you have cash on you, as their is no eftpos facility here.
PS - Look out for the small watch shop located just up Kuta Theater. It is from this shop that the beach and street venders buy their items and you can negotiate very reasonable prices as you miss out on the middle man.
