This should now also protect my sewing apron and my schoolbag from getting more holes in them... which has been a problem for me transporting my scissors back and forth from school. It's working pretty darn well for something I put together in less than an hour. Hahaha
Then I cut my pieces out of leather. This was leftover material from my Asuna armour, specifically the straps for the shoulder piece.
Then I sewed the 2 main pieces together, leaving a small seam allowance. (These were simply top stitched, insides together.)
The end result is a simple, yet functional holster. :)
