Wash and iron both fabrics.

Fold the red fabric neatly in half lengthwise from selvage to selvage.

Apron 

Start at the top of the fabric with the fold on the right. Mark a 6.5-inch line perpendicular to the fold and mark a 1-inch line 90 degrees down from the end of the 6.5-inch line, as shown above. The bottom of this 1-inch mark will be POINT A

Make a little mark 1-inch below the 6.5-inch line at the fold.

Make another little mark 16-inches down from this 1-inch mark on the fold. (I used my pencil, which will come out when the apron is washed but you might want to use chalk if you want to give it as a gift.) We will call this mark POINT B.

Mark away from the fold  13-inches from POINT A. This will be POINT C.

Mark a diagonal line from POINT A to POINT C

Mark a straight line down from POINT C, 13-inches from the fold for 20-inches. The end of this line will be POINT D. This will be the skirt of the apron. Make a straight horizontal line from POINT D to the fold.

Now cut the whole thing out!

Pocket 

Cut the pocket piece 17-inches x 10-inches.

Tie 

Fold the rest of the blue fabric in half from selvage to selvage. Cut three 4-inch strips from selvage to selvage and cut off the selvages.
