The basic form of your frock is almost done. We just need to give it a hem.
1- First try it on right side out. It is easiest to use a friend or a dress form. Place a pin in the center front, center back, and side seam where you want the hem to hit. (use your measuring tape to measure from the floor to the hem line to make sure it is even all the way around.)
2- Add about 1 1/2" for folding and then cut off any excess.
3- With frock inside out fold bottom edge up 1/2" all the way around and press.
4- Fold up another inch all the way around and press and pin.
5- Edge stitch around entire frock, backstitching at both ends.
Good job! Your basic frock should be done now and look something like this. Next we will make some optional embellishments.
