Ok, there must be an easier way. I have some oil hide, and I want to make a gusseted bag. The front and back are separate (see pic #1), so I want to run the gusset down the side, across the bottom, and up the other side.
The problem is the corners. I have a plan, but I don't like it. Make a slit in the gusset edge (pic #2)... But that leaves a gap in the corner (red bits on pic #3). I fix this by making a corner fill triangle (green thing in pic 4). The problem is, that's an extra step, and I'm not crazy about the look of the triangles. Also, on a smaller pouch, it'll be a real pain to get aligned, punched, and sewn.
So I'm looking for other ideas, or critiques of this plan... Other than rounding corners or making the back/front one piece. Any other techniques out there?
