I'm just joking with you ......I remember you from some of the other forums. You're always welcome to email me and I'll help you out.
It takes a long time to truly master leather work.....hell I'm still learning every day! Don't get frustrated.....keep trying different techniques and by all means utilize forums like Leatherworker.net to enhance your skills. I've seen some fine craftsmen on this site! Perfecting your skill set will take time and it's not going to happen overnight. It took me a long time to get the color tone down from the first strap you posted. Funny part about your post is I recently started putting together a new product line and this is the first strap I wanted to offer. I had to go back through my notes to figure out how I did it . I'll post some pictures on the forums of the prototype in a few weeks. Like I said, I'm in the process of redesigning the entire line.
With that said, I'd keep a good record of what you've tried that way you can always reference it when necessary. Every strap I've ever built (prototypes) have a detailed build explanation with them. This list defines the hide, stitching style + punch used, dye colors (if applicable), etc... Good luck and send me an email if you need anything.
