Hi there. 
Not a leather worker or anything, but I want to make a wallet like this one. 
So being a newbie and the fact that my country sucks, big time, I'm buying sewing thread online. 
I've got some leather (is artificial / an imitation how do you call it) not so thick like this one but I want the 
hand stitching that I would make to stand out like the one on the picture. 
So the question is, would size #207 (Tex 210) would be thick enough for what I need, 
or maybe #277 may be better? 
I have no idea how big these threads look, because there is no shop in our country that sells them. 
Thank You.
