Help with square corners on wet molded pouch

[bigsig11010]

I’m making a wet molded pouch that is more or less square. I’ve got the form and the leather is in the shape I want but the corners are wonky. I’ve tried to search you tube but the videos I’ve found are for flat corners or gussets. There should be a way to make a cut that will result in a more square corner but I can’t figure it out. Project is the mid pouch on the back outside of a scout carry sheath where you would carry altoids tin or brass tinder box etc.  Thanks to anyone who can assist.

Try using a small spring clamp on the corners; to pull the sides together. Use pieces of scrap leather between the clamp and your piece to avoid the spring clamp leaving an impression of its jaws on your piece

One of these, that depending on the size of your piece. but I'd go as large as possible

But you'll not get perfectly tight corners without cutting the leather

Where's the bottom "wing"? You need to unfold the bottom, then trim oversize all round so you can re wet it and clamp all round. Then force it around the corners with a bone folder or similar. Got to be wet. After drying and stitching, trim to final size.

I am assuming you are trying for something like the following photo where you have pouch attached to a shealth:

You seem to be trying and fold under the bottom of the pouch during your wet molding. I would approach it using a form where the wet leather is placed over the shape form that has the side edges extending about twice the height of the form, place the wet leather over the form and clamp one side down, form the leather over that side and then move to one of the other sides and clamp. I would probably use a 2 inch "O" ring to shape the leather. Let dry for about 24 hours and then damp wet areas that need to be reshaped.  

This topic shows the shaping tool I would us.
