You're welcome! It's tough to get started all by yourself, especially if you aren't familiar with the basics. I used my airbrush to do the colors, then I antiqued the whole thing. Last, I buffed it with sheep's wool. I do have a variety of small brushes for detail work as well, like the flower centers, and for other techniques like dry brushing. If you can't get your hands on patterns, pick a design you like and carve that. The process is the same. Here are a few holsters I have done.
Alas, I have only been doing this for two months, so I am by no means an expert, but I am recently familiar with your dilemma, so take my advice with a grain of salt
