These are the cutest little dress ups that are super practical and your kids wont grow out of them in six months. I also liked these particular ones because kids don't have to take their clothes off to wear them.
The first step is to cut out a doubled piece of fabric that is 20 inches wide and 16 inches tall. Like shown above.
Then you want to surge (optional) and sew (as close to the surge line as possible) 3 (2 long sides and 1 short side) of the 4 edges of both pieces of fabric put together. It will feel like you're sewing a pillow case.
Then flip all the fabric right side out to look like the picture above. Iron and put to side.
For the top part of the apron you need to cut out a doubled piece of fabric again, this time 10 inches wide and 7 inches tall.
If you want a non rectangle shape for the top draw a little sweetheart neck and cut out. It should still be the same measurement as the rectangle top, just shaped differently. For the rectangle surge and sew the 3 sides, this time 2 short sides and 1 long side. For the sweetheart neck line, surge and sew the 2 sort sides and on sweetheart sew about 1/4 of an inch in while following the shape. As shown above.
Flip right side out, iron and set aside.
For the Aurora piece I cut out a doubled piece of fabric, like the one above and sewed all the sides other than the top long side ( which should be the same 10 inches wide, to fit with top piece of apron). Flip right side out and iron.
Lay both raw open edges of the top piece and triangle piece on top of each other.
Pick up your skirt and surge the top part that was left open for a finished look and to prevent fraying. Use a LONG straight stitch and sew right under the surge line. Once you reach the end of your fabric leave long strings on the end of fabric so you can pull them and ruffle the bottom skirt.
Once you have ruffled your fabric to the length of of the top piece of the apron ( about 10 inches) pin it to the top piece and triangle piece that you laid on top of each other earlier. All raw/surged edges should be pinned together. Sew on top of ruffled edge about 1/4 inch down. Make sure all fabric is flat under the ruffles and you're not snagging anything.
Once you have secured you stitching flip over and you should have this!
This is the back of one of them, just so you can see what it looks like. I took the seam on the back side and surged the excess off so it was 1 clean line instead of 3 different fabrics sticking out. Then I sewed what I surged, down flat. But I am OCD like that so its optional.
Add a 16 - 18 inch piece of ribbon for the neck ( burn edges of ribbon so there is no fraying ) and add at least a 46 inch piece of ribbon to evenly go across the top of skirt ( over the seam line ) and over the back edges, leave an even amount to tie. You can also add 2, at least 10 inch pieces, of ribbon for the neck on each side to tie, rather than having a neck loop so it's more adjustable.
