Hole Punch at 90 Degree Corners?

[doubleh]

I believe "radius" would be a better description of what you are meaning and, yes, a hole punch is good for making them.

Important: Do not use the dimensions in the posted pattern!

Yes, I already posted one warning. But even after I modified the pattern slightly to allow for rounded corners on the pockets, it was still too tight. I should have allowed more room to make it easier for the checks and register to slide into the pocket. I ended us whittling the reinforcements between pocket pieces in order to make it usable. This added maybe 4mm to the length of the cut-out, but even then the tolerances are really too tight.

The main thing I noticed is that the inner and outer pieces are the exact same length from what I can tell.  That isn't ever going to work if you wish to fold it.  And obviously you do.  The outer shell in my opinion, and this varies according to thickness of leather, needs to be at least 3/8" to 1/2" longer than the inner piece.  So in mm, about 9.5mm to 13mm or thereabouts.

You seem to be very cautious and wanting to draw a perfect template.  Nothing wrong with that but don't let it become paralysis by analysis.  I'm one of those who is pretty lucky in that I can look at something and pretty much recreate it without resorting to detailed templates such as yours.  Not everyone can do that I realize.  But my advice is to buy some cheap "practice leather" and just begin creating.  You might be surprised how simple it can be.  And still get great results.  

I have bought sides from Springfield Leather Co. from their discount table that have been perfect for this.  I think on their website they call them $35.00 sides or something like that.  They used to be even cheaper.  But you get an entire side of usable leather that is good enough for actual projects and definitely good enough for practice.  Some that I've gotten was extremely impressive but they were one-offs I guess and they just wanted to move them.  I'm sure a leather company in your area might have similar hides.

Good luck and have fun!

Or to be sure (without a template) maybe leave the outside (folding piece) over long and cut it to size when folded over.

Already made it and using it. You can see a photo (and issues I ran into) in Critique My Work.

The leather is light enough that it folds. The only issue is that the reinforcement creates a sag in the single layer portion. Because this is light leather, toyed with the idea of a solid piece of leather in the fold and cutting slots, Due to the outer layer readily showing creases just from carrying it, a revised pattern would use a heavier weight of leather for the outer piece and two sections of lighter leather to form the pockets. That removes the reinforcement at the sides and should remove the sag.

There will definitely be another checkbook  A family member asked me yesterday for one to replace another that's coming apart.

take out the "reinforcement", problem solved. All the patterns for check books i have use two pieces inside for the pockets not one with a slot in it. your overthinking things to much.

or you can line it completely and just use a card slot for the check book backing to fit in. But my point is the leather at the fold has to be the same thickness all the way across the item or it will do weird stuff.
