Decided to start a new topic. My plan is to initially make a non-functioning pair in both leather, and vinyl. The insides will be solid. Then, using MMM's idea, I will attempt functioning ones by using pieces of metal as support inside.
To me, it's not that important if they function. Fett has a ton of other pockets here and there, and these are pretty narrow for someone with gloved fingers to get inside.
This is just the vertical flap, using BB's 4.5x1.85 figures. The stitching is simulated, since this is only a test run. Although, if I made leather ones, I could do the same thing.....but then the stitch count would probably be off!
