Cut a rectangle 30 inches wide by 33 inches long out of each of your main piece fabrics (you'll have two total 30x33" rectangles). One will be for one side of the apron, and the other is for the other side, so make sure they are coordinating.

To get the arm holes, fold one of the main pieces in half lengthwise, and then make a mark 6 inches from the fold and 9 inches down the side. 

Using a fabric marker, or making an indent with the handle of your scissors, make a curved line from the two marks, and then cut along that line through both sides of the fabric to make an arm hole on each side.

Repeat with the other main piece. Fold it in half like the other piece, then lay it on top of the already cut piece, and cut along the curve, using the first piece as a guide.

Next, cut out the shoulder straps (2.5” wide by 25” long (cut 2)), waist straps (2.5” wide by 40” long (cut 2)), and pocket pieces (17” wide by 10” long - cut one pocket in one fabric and the other pocket in the other fabric.)

Fold the straps in half lengthwise with the right sides in. Sew along the edge. When you get to the end of one side, fold down the end and sew, giving it a clean edge.

Repeat that same process for all four straps.

Using a safety pin, pin one side and push it through to turn it right side out.

Press the straps with an iron, and then add a top stitch down each of the long sides of the straps and over the side you turned in.

Prepare pocket piece by pressing all sides. Fold over each side about a half inch, and then another half inch, and press.

Sew a top stitch on the top edge of the pocket.

Place pocket 7-1/4" from raw edge sides and 14.5" from top.

Pin in place.

Once the pockets are in place, top stitch the 3 sides of the pocket that have already been folded and pressed over to sew it to the apron.

After the pockets have been sewn on each side, find the middle of pocket (7-1/4" from the side) and sew down the middle, creating two pockets.

Lay the apron flat with right side up.

Pin the finished short straps to near top of the apron, about a 1/2 inch in from the side (this allows for seam allowance). The unfinished edge of the straps should be in line with the raw apron edge.

Pin the finished long straps near the waist part, about 1/2 inch below where the arm holes end on the side. 

Place the other main apron piece on top of the other main piece, right sides together. The wrong side should be facing you.

Make sure all your straps are laying inside the main apron pieces so they're in the right spot when you turn out your apron!

Sew all the way around with a half inch seam allowance, leaving a small opening at the bottom to turn it right sides out.

I clipped little slits around the curve for the armholes and trimmed the corners a bit; this will just give it less bulk when turning it out and help it lay more nicely.

Turn the apron right sides out through the hole in the bottom. Sew all the way around the apron using a narrow top stitch.
