Reversible Half Apron

This wonderful apron pattern was found at MY LONGEST YEAR.
Run over to her blog and see some of the other wonderful projects created by this awesome seamstress.
Basic Apron Without Ruffled Bottom:
Materials Needed:
2 pieces complementary fabric, 15"x24"
1 strip of fabric for top binding & apron strings, 4"x 55" (or use a measuring tape to determine your desired length - you may have to sew two lengths together)

Right sides of both apron pieces together, sew bottom and sides; clip the corners (figure b.)

Turn right side out and press.
Using your machine's longest stitch, sew a basting stitch 3/8" from the top edge, leaving a long tail of thread at the end.
Pull the top thread carefully, loosely gathering into a slight "ruffle" (figure c.)

Press the fabric strip in half lengthwise. Open and fold the raw sides into the center. Press. Fold closed and press again (figure d.).
Center the fabric binding over the gathered top edge of the apron and pin in place.
Starting at one end of the binding, topstitch the binding closed, stitching close to the bottom edge (figure e.) (Optional) Apron with ruffled bottom:
Fold a 3 1/2" x 36" length of fabric in half lengthwise, wrong sides together.
Using the longest stitch on your machine, sew a basting stitch 3/8" from raw edge.
Pull top thread carefully, slightly ruffling the fabric until it is approx. 23" long.
Place one piece of apron fabric right side up. Line up the raw edge of the ruffle with the raw bottom edge of apron fabric, ruffle pointed toward the inside. The ruffle should start and end 1/4" from the left and right edges of the apron piece (figure f.).
