There must be darts or wedge-shaped pieces taken off the front panel to match-up with the crescent shaped bottom.  How would one calculate that?  I'm stumped as suggested by the unfinished second photo

There are darts, and the piece might look something like this...

And this is what the back (to that front) might look like... 

This image doesn't look like it will match up to the front piece (because these are slightly different resolution JPEGs, but if you'd like I can post PDFs of these parts so you can print them out and see how close they match up. This design is still in the rough stage, and may need to tweaking, so please keep that in mind.

...and here it is. I hadn't compensated for any volume inside the bag (sorry that my poor pea brain works this way, only one step at a time), so here is a revised front.

Hey LatigoAmigo.  WOW! I'm blown away! It would have taken me $300 worth of watercolor paper to come up with anything close to this!  The SM TFPB is 11" W x 15" H x 5" D.  I'm looking for a smaller dimension of the bag body: 8" x 12.5" x 4" and probably lose the gusseted side pockets in favor of two slip pockets on each side. As mentioned above, I want this to be a single, wide back-strap sling bag. My plan is to use Horween Dublin Tan with a sheepskin backside and strap.

Would a PDF be easily scalable to my desired dimensions?  

I see you're located in Santa Rosa and I live in Indio. Do you have a shop?

Here are PDFs for the two pieces we've discussed, to your dimensions, so you can see what they might look like. I always have to make a prototype and sew it together before I cut any leather, as there always seems to be some necessary adjustments. This may or may not be exactly what you are looking for, but it has been fun for me to go through the exercise with you.

I do, a Tuff Shed in the backyard, but I don't this to sell things, I just like designing.

hey again. I got the back to print in actual size vis portrait on 8 2/2 x 11 paper but the front pdf is just the bottom section and in a different scale. am I doing something wrong?

thanks again

in actual size

The actual size is much larger than a standard sheet of paper. In order to print it in actual size, you will need to "tile" it, which will print the image onto many sheets of standard (8 1/2 x 11) paper that you can tape or staple together, or better yet, you can have it printed on large format paper at a place like Kinko's. When you open the file, drag your cursor to the lower left of the image, and Acrobat will display the image size so you can see what to expect.

I would suggest the front panel with the two darts , might be better with small circular punch holes at the "V" top (say 1mm dia)  to stop any possible splitting in the long term, probably not needed but just a safety measure

Thanks.Are you suggesting round sewing holes rather than using my pricking iron with diamond shaped holes? 

 My next step is to buy a yard of pleather and build a prototype. Hoping that assembling this will give me an idea for some well placed rivets.

No the stitching stays the same, it's just the top of the V the sharp point can on occasions tear, but if you just punch the tip with a punch so it becomes a circular cut it normally stops any tearing tendancy hense the very small punch size
