On the front of the apron, mark an inch from the bottom all the way across. Use chalk so that you don’t cause any stains. Fold up the inch of the bottom toward the back of the apron and iron it all the way across. Ironing will make sewing your hem easier. Use a medium straight-stitch to sew an 1/8” from your zig-zag stitches all the way across.
Hem the top of your bodice in the same fashion, folding in an inch, ironing, then sewing across. Fold in each of the sides of your top just a ½”, press, and sew.
Your top is almost ready. What you really need now is a few straps.
