All About Pocket Knives

I have been playing around with a little leather work, just trying to learn some of the basics.
Last week a co-worker asked if I could make a belt pouch or sheath for his Leatherman tool. Here is what I came up with:
Since he uses the tool daily, I didn't want to take it with me. So I drew an outline of it on cardboard. Today I made a mock-up of it out of popsicle sticks.
I had picked up a bag of scrap leather at Hobby Lobby for $5.99, along with some needles, waxed thread, and a few other items. The rivets and snaps I ordered off Amazon.
The scraps are a soft, lightweight leather, and not really suited for knife sheaths, but it is great to use for learning. So far I have made a replacement pocket holster for my pistol, a leather handle wrap for my old slingblade, and now this sheath. I have only used up about $2 worth of the leather!
The belt loop is a heavier leather that I got from my Dad. It is much thicker and would have made a better sheath, but I don't want to waste it before I can do better.
I wound up cutting the edges too short on the side, so instead of overlapping the edges and using a Saddle stitch, I butted the ends together and came up with some kind of cross-stitch pattern. It looks weird to me, but I am not charging him for it so I shouldn't hear too many complaints.
Oh, and some free advice: if you want to round the corners on a piece, but forget to do it until after everything is put together, heavy toenail clippers work great!
