Pull drawstring through and hem pant legs. If you've made a dress, you will need to make an apron. You will need two rectangles, one for the front and one for the back plus two straps. For the apron rectangles, measure the width you want. The length is determined by how long you desire the apron to be.
Measurement is usually from the collarbone to ankle.
Sew along the outer edge of the turning seam. Now measure from the collarbone to the middle of the shoulder blade. This is the length of the strap. Fold each strap in half lengthwise and sew a seam down the long side. When you reach the end, turn the fabric and sew ONE short side.
