Step 3: After marking the fabric, fold together the fabric so your markings meet to create a pintuck.
Step 4: Once you have marked and pinned all your pintucks, press down the pintucks with an iron. I know ironing can be tedious but in order to get a nice clean finish you will not want to skip this step.
Step 5: Now flip each pintuck up and sew along the inside crease.
Step 6: Before we sew the shirt together, the next step is to hem the neckline. I like a thin classic rolled hem between 1/4″ and 1/2″ wide. To do this just fold the fabric in 1/2″, then fold it over one more time so that no raw edges are showing. Iron, pin and sew.
Step 8: Keeping the shirt inside-out, use the same technique from Step 6 to hem the sleeves and the bottom of the shirt. You can keep the bottom straight or you can round it like I did in the shirt for my sister-in-law.
