About 1/2 in. down, gather across the length. Pull up the gathers a little. You will adjust them later.
Ok, to weird but it looks like I forgot to write down for you to cut out a piece for the apron. Ok, this will go around the dolls chest and so measure that and then about an inch wide. Add a half inch to the length so you can fold it in. Understand? Ok, fold the long edges in and press fold the short edges in and press. It should be about a half inch wide. You can make it narrower by pressing down slightly more than 1/4 inch on the length if you want.
How did I completely forget pieces?? Anyways, you’ll have to but out the shoulder bands. Those should be about 1 1/2 inches wide and 4 1/2 inches long. You’ll need two of them. Anyways, fold right sides together and sew across the length. Leave the two ends open. Turn right side out. Press.
Hem the apron ties on all but one short edge and fold that edge to fit behind the apron band and stitch. Repeat for the other on the other side. And that’s all there is to it. If you have any questions, please comment. Have fun :)
