Now, turn the paper back over, and sew on the paper line between #1 and #1. Set your stitch length to small. It will secure the fabric better and make it easier to tear off the paper later. Start & stop exactly on the end of the line.
Turn the paper over so the fabric side is up, and fold back Fabric #2. Finger press. See how Fabric #2 now covers the pattern #2 when you hold it up to the light?
Sew on the line between #1 & #2 with a short stitch.
