Now turn the pack n play sheet right-side out and slip it over you mat.

Step Three: Line up the tail ends of the side panels and pin them to one short end of your pack n play sheet body right sides together. Make sure the serged sides of the side panels face inward. The ends of the side panels are just hanging down, unfinished.https://www.biloban.com/collections/pack-n-play-sheet

Here is the serged end. It's hard to see the wrong and right sides of the this particular fabric, so I apologize. Make sure to sew everything "right sides" together.https://www.biloban.com/collections/pack-n-play-sheet

Step Four: Pull the unfinished tail ends of the side panels until they meet with the opposite end of the pack n play sheet body that you just serged... this will cause the end to fold in order for those side panels to reach the opposite end. Now pin the side panel ends in place and serge down that side like you did the other side.https://www.biloban.com/collections/pack-n-play-sheet
