Here's where I went wrong. I cut my pattern way to small, My welt was uneven, my stitch grove line was way off on the back of the sheath, when i drilled my stitch holes I didnt get them straight causing my uneven welt to "pop" out. There were some points where the welt wasnt covering the stitches, and when I inserted my knife it cut them rightaway.....
Now, as soon as I started this, I knew it wasnt going to be a work of art, but I thought it would still be functionable. What I was trying to do was make a "one piece" sheath with one stitch line for a four inch blade.....I just put everything away and will do some more reading on here before i start again. If anybody has any patterns that they would like to share, I'd be very gratefull. My ultimate goal was to give holsters a try, after my sheath disaster, im not sure if I'll ever be able to.
Thanks for listening everyone, Hotwing.
