The hemmed edge will become the bib/top portion of the apron. Cut off the hem and fold in half with the intact seam as the center of the fold. Cut out the curve portion for the “arm” area. Shorten the leg to the length you desire and cut the bottom of the apron to your desired shape. In my example, I made this apron 24” in length and “curved” the hem.
Cut 2 pieces of bias tape to serve as the ties for the apron. The length is based on your own preference of whether you want the ties long enough for making bows. I like long ties at both the neck and the waist. My bias tape strips are each 60” long. I measured the “arm” curve (10”) and added 20” for the neck section of the tie and added 30” for the waist section, hence 10” + 20” + 30” = 60”.
Pin the strips in place, and attach by sewing. I just turn the ends inward and stitch them down to finish.
