First of all, I apologize for not introducing myself before asking for some help and my language using if it is quite weird to some of you (English is not my first language). Honestly, I have never been in a forum like this before, I mean English-version forum with so many English-language people. I'm Asian. When I was in my country, if I wanted to look for help in a forum, just went straight to the point. And when I read some posts here, I saw that they just asked. (I didn't know that they have talked about themselves before). So I kinda shocked and ashamed when some of you react like that. That's my bad. So sorry.
Then, about the pattern, I swear that I search on google, youtube, tandyleather.com, or even this forum as well. But they are not like what I want. Maybe to some of you, this kind of wallet is super easy to modify or make, but not me. I just knew this art few days ago. I fall in love with it. I also looked up for some leather classes around my area (Georgia), but they only teach how to make a belt or business wallet. That's why I come up to this post. You have no idea that how much I want to learn it. I even think about driving 12 to 14 hours to Texas to take a class of making leather wallet. If it was just simple like go to the store, buy some leather, and then make it, I would. But it's expensive, tools and leather. That's why I ask here cuz I think It's faster and easier.
Anyways, that's my bad of not introducing anything. Just like knock a door, step into someone's house without permission. That's too rude. I know.
I thank all of the replies above, especially someone who shows me some hints and video which help me a lot to look up for the pattern. Next time, I will know what I should do before asking for help.
P/S: I'm only 20, still too young. And, the Asian culture and American one are huge different, so hope all of you do not mind about my behavior. Once again, sorry and thank you so much!
