Joe,
Now we have some information to work with.
I would suggest finding a guild or a Tandy Leather store.
most Tandy stores teach basic leather working and with a little bit of effort you should be able to make the crock wallet you are showing in the photo.
Leather work is like most skills built one simple skill after another.
I would put my efforts into pattern development and the lacing technique.
Don;t make the newbie mistake by not leaving enough room for the outer shell to wrap around the inner components when closed.
The lacing while simple requires and attention to detail that can lead to frustration if your not prepared for it. i.e. inadvertently twisting the lace only to discover the error at the last moment and having to re do it.
Your Tandy mentor will provide some starter kits that have all been precut with detailed instructions so you can learn the skills without a big investment.
Regarding the black wallet the disciplines involved are in most part the same. Pattern making, ease, and fit that unfortunately is where the similarity's end. Sewing with a machine is a simple process but like anything it takes a bit of skill building and after a few tries you should be OK.. The key is having access to the proper equipment for the job at hand. While most machines look alike they sew or stitch different textiles differently. Machines can range from a couple hundred dollars to thousands depending on the model and it's capacity. my next machine is going to cost me about $5000 and it won't sew anything as lite as a wallet.
May I be so bold as to suggest starting slow without spending lots of money, get some skills, expand on them and build your tools as you need them. Again your local Tandy operator will be glad to help along the way.
There may be a guild in your community that can be helpful as well.
Good luck Most importantly have fun and let us know how things are going for you,
Al
