|Here is one way to get smooth, rounded corners|
on patch pockets like these
|Because you didn't backstitch, you'll be able to pull on the loose|
thread ends--just one of them--to create a slight gather.

|Here's how the front is starting to shape up. You'll want to |
adjust the amount of gather until you get a smooth curve.
