Umbrella Turns Zipper Pouch

I recently made this zippered pouch bag using the fabric of a broken umbrella. I followed this tutorial and just before closing the lining (also made from the umbrella fabric) I decided to stitch down and cut off the edges at the bottom so the pouch would stand up on its own (you´ll find plenty of tutorials for flat-bottomed pouches online). I used some jeans fabric remnants to interline the bag for stability and topstitched with thick red thread. The jeans fabric makes it a bit heavy so if I made another one I would probably use fleece or stabilizing interfacing.
