Here’s a photo of some leather work I did on the portable altar. The leather is a Lattigo leather, very thick, so I had to compress the leather for the post to have enough clearance to set the snaps. The bottom is fixed, I used Loktite to prevent the screw from coming loose during use.
I added a couple of crosses and rounded the corners. This is VERY easy to do after I figured out how to set the snaps.
