This was my first attempt at making a pouch......with lining too!....and a zipper!!.... So, I found this great tutorial by Indie House. I used what I already had in hand, which wasn't much - some leftover fabric that my sister had previously given me and I didn't even have any interfacing! Guess that's why it didn't turn out as 'boxy' as it should. So, check out Indie House's tutorial. Her pouch is just too cute!
