Im making the 6-12 months Sleepover Pyjamas and I've sewn the first part of the facing (step 1). Step 2 says to understitch the neckline section and I'm a little confused. I've ironed the seam allowance away from the neck so am I just stitching the main fabric? Sorry if this doesn't make sense. It's hard to explain.
I should add I'm not dong the ruffle. The diagram shows the ruffle version so perhaps it's not relevant to me???
