Instructions
Print out needed pattern pieces.
Lay your green fabric out somewhere that you can easily measure and cut.
Here are 2 cutting guides-one for adults and one for kids. Fold your fabric in half but only the amount you need to cut (like if you are making the adult size, you'll need about 27 inches to work with but need to save the excess so you can cut your second piece next). The measurements on this guide are accounting for the fabric being folded in half (meaning that the 5.5 across the top of the adult's, for example, will make the apron itself 11 inches across the top when you actually make it). Follow this guide to cut out the shape of your apron. Remember, it's an apron-if you are close to these measurements it will fit great! Here's the children's one.
Here is the adult size one.
Now you need to make the little zigzag across the bottom. Use the pattern pieces above to guide this.
Next, you will need to cut your black ribbon the width of your apron (18 inches for the kid size or 26 inches for the adult). I like to cut it just slightly longer than my width-so maybe add about 1 extra inch.
Cut 4 pieces of yellow ribbon each 2.25 inches long.
Cut 2 pieces of your red fabric to make the collar. (From pattern pieces.)
Finally, cut your ties and neck strap. The ties should be cut 5 inches wide by 26 inches long for the kid's size and 5 inches wide and 40 inches long for the adult's size. The strap should be about 5 inches wide and about 19 inches for kids and 23 inches for adults.
Sew our red collar pieces together around all sides except across the top. Snip the sharp inner points just to the edge of the thread but not cutting through the thread, then turn right side out, use something sharp to push out the points, then press it flat.
Sew your black ribbon to the front of the apron from one side to the other just below the armpit curves. Sew a line across the top and across the bottom.
Overlap your yellow ribbon pieces by placing them first above and below your black ribbon, then adding the two sides. Pin it all carefully in place (you could even glue it down a bit to really keep them in place-this part can be tricky). Sew a square around the inner edge of the four pieces and the outer.
Sew your straps each along the long side and for the ties, along one short side as well. Turn them all right side out and press them flat.
Place your red collar across the top of the apron and place your straps in place as well (see image).
Place your other apron piece on top and pin everything in place.
Sew all the way around, making sure to catch everything that you need to like the collar across the top. Leave an opening to turn it (I just did it in the side below the ties).
Turn it right side out and push out all of the corners with something sharp (I use the ends of my scissors.)
