Thanks for the input, Sam.
I'm using a Bernina home machine now, and its doing a good job, but I'm trying to keep the big stitches to a minimum. I've got a big ole pop riveter which I use for some of the strap attachments on the heavier straps. It does a great job, and looks 'hardcore' as well.
It has been taking a lot of time, but so do all of my projects, and I'm happy to sleep when I'm dead.
The colors have been a lot of fun. I've done a lot of tiedying in my past (don't ask), but the skills have held over, and I've been able to do fun stuff with canvas.
The bag part is pretty well designed, I think... I spent some time in a few stores reverse engineering a few bags and deciding how I wanted the main bag/flap system to work, including how to keep water out. The strap is my biggest area of fiddling right now. A simple 2" webbing strap with cam buckle is what I've got now, because I happened to have webbing and a cam buckle lying around, but I'm figuring out a way to do a fully padded strap with release buckle.
Anyway, don't worry, I'm clearly not meant to make these professionally, so you don't have any competition.

I'll be happy if I get one good bag to wear around. I'll post a picture of it full of beer cans when I finish.
peace,
sam
