Finishing off a specific pattern - Jarol pattern JX265
I am sewing together the rompers from Jarol pattern JX265 New arrival. However there seems to be something missing. It explains how to sew the straps to the front, but not the back. The straps are not long enough to stretch from the front, over the shoulders and down to the waist at the back. But if that is how they are sewn together there aren't any fasteners to open so that it passes over the babies head!!
I would be most grateful if you can help
