Hi Mia,
Before sewing for the first time, practice on some scrapes of fabric. It will be important to learn to sew straight and even. Curves are tricky so practice those too before sewing your apron.
When you are ready, here is how to sew your new apron.
Start with the pockets. Put one pocket piece and lining right sides together and sew starting at the top by the narrow neck and finish at the top of the narrow neck on the other side leaving an opening at the narrow neck. I like to keep seems about 1/2 to 5/8 inch from the edge and have your needle down when turning so that when you make your turns, the fabric doesn't slide around.
Next, cut off the three corners and clip into the curve as shown below. Be sure not to cut into the stitch line anywhere. Note that you don't clip the corners at the narrow neck.
Next turn the pockets right side out using something relatively sharp to make your corners sharp, but be careful not to poke a hole. Press the pockets so that from the right side you don't see any lining.
Zoey's pocket has trim on it, but I didn't think your pocket needed extra trim. However, if you want trim, now is the time to sew it on.
Place the pockets on the skirt front as shown below or as you see on Zoey's apron. Make sure you are far enough from the outer edge so that when you turn the sides over, you won't be turning it onto the pockets. (Call me if you have questions.) Sew them to the skirt by starting with a small triangle on the right pocket on the outer corner and ending by sewing to the top of the long side of the pocket. The left pocket is reversed. Start by sewing the long side of the pocket and end with a small triangle on the short side. Note how close you are to the edge. Again, look at Zoey's apron for an example. When sewing pockets you will definitely want to have the needle down when turning corners. You might want to practice this before sewing your pockets on.
I surged the bottom of your skirt hemmed it, and put the trim on the bottom edge. It is easier to do this step with a special foot so I did it for you.
The skirt below is what your apron should now look like.
Next, sew the ties on the bodice piece. Yours are already sewn on.
Put the right sides together of the bodice top and lining. The ties should be hidden inside where you won't sew the strap ends. Sew all the way around leaving the bottom section open. Cut off the top corners and if you want a nice look, trim the lining a little closer to the stitch line as shown below. I surged the bottom side of the lining for you.
Turn the piece right side out and press it making sure that the lining is hidden on the back side.
Next, pin the bodice to the skirt with right sides together. Start in the center of both pieces and work your way to the outer edges. You are going to see how much to turn the edges under on the skirt so that the edge will fit perfectly inside the bodice piece.
Once you know where to turn the outer edge of the skirt, turn, pin, press and sew the edge of the skirt before you sew it to the bodice. You can unpin the bodice from the skirt if that is easier for you. I usually do just so the bodice doesn't get in the way.
Next re-pin the bodice to the skirt and sew it together leaving the lining out of your stitches. Make sure the skirt sides fit into the bodice piece.
Next, pin and press the lining down so it's nice and flat. The bottom edge is surged so you don't have to fold it.
Below is called "stitch in the ditch". You basically sew right in between the two pieces of fabric because you don't want your stitches to show on either piece.
Tada--You are finished except you may want to press it one more time and my mother taught me to always cut off my threads short so that you can't see them. Otherwise, people can tell you are a new sewer.
Send me a picture of your apron when you are finished and more pictures of treats that you help to make wearing your new apron.
