Sewing Around Corners - Made Easy

So, this is the part that I had to research.  How do you sew around the corners for a cushion?

Basically, you should watch the video.  You need relief cuts.  You need to position the fabric together using the darts.  Use fabric tape to hold the fabric in place.

Instead of making a 90 degree turn at the corners, make 2x 45 degree turns and have 2-3 stitches between them.

I am pretty sure I showed the sewing in other videos.
