So I've been making these wallets for a little while now, and have a question about my process.
I glue all the card slots onto the liner and assemble the entire thing before gluing it to the outer shell. This means that I end punching the stitching holes last ( I use Tandy's 4 prong Craftool punch). This seems to work fine, but occasionally, the force needed to punch through multiple layers of 3oz inner plus the 4/5 oz outer shell seems to be too much. I have to wiggle the punch out and sometimes the holes just seem to big after the stiching is done because I had to whack the punch so hard to get through the layers..
This picture shows what I'm talking about:
So my question is:
Should I be punching the holes for each piece individually, THEN gluing them together? This seems like it would result in cleaner stitching, the only problem being that the holes never seem to line up. I've tried it before where punch the holes for the outer shell, then punch the holes for the inner, and try to line them up when gluing together but I always end up having the needles going through at crazy angles and had a tough time with that.
The attached picture shows what I'm talking about, (taken from Corter Leather) I just wonder how the heck all of the holes stay lined up, as cutting out pieces by hand always seems to ensure slight variances in dimensions.
Thanks for taking the time to read this!
