Boxing sewn to top, ready to attach to bottom

We have sewn the top to the boxing, and are ready to attach the bottom in the same fashion.

This will create an inside-out cushion.

I mention that we "clip the corners."  Basically, after we sew the corners, we clip the extra fabric off the inside corners to make it easier to turn it inside-out.

We unzip the zipper before sewing.  That is easier than unzipping it after we sew.  Remember that the cushion is going to be inside out, so the zipper pull will be on the inside.

We used the zipper pulls that have "locks" on them, so that they have to be pulled on to unlock.  That would be a real pain to unzip from the inside.
