Sewing a lined zipper pouch

[bartlettpear]

Does anyone know how to sew the zipper in so it's square and not rounded on the top edges?

Here is my bag with the wonky edges. How do I make them SQUARE?!

You have to make sure that your zipper teeth are facing your lining when you sew up the ends and if you want to make sure they are really square your best bet is to add some fabric tabs to the ends of your zipper so when you sew up the sides you are not sewing over the zip. Here a tutorial that will help you with that. You should also clip your bottom corners of your main fabric and lining fabric before turning the right way out so that you dont have a bulk of fabric at the bottom corners. Shout if you need any help. xx
