Isn't she beautiful? Ack, my heart!
Step 1: Snippy Snippy
Don't clench up about not having exact measurements. There's plenty of wiggle room built into this dress since the front overlaps and can be hemmed up the front to make it smaller if needed. Just cut everything overlarge.
Stitch the skirt halves together. You can hem the bottom now if you like or wait to see if it is suitable length then hem it.
Overcast the sides (not the arm holes! I did that the first time. I disappoint myself) and the shoulders of the fronts and the back.
Quick with the sleeves. Isn't this easy?
Sleeves to the bodice. Starting to look like something.
Ruche the sleeves. To be honest, I don't know what ruching (?sp) is. Did I mention that I have no idea how to do this? But I always think I can figure anything out if I try. This supposition is frequently wrong but I never learn from that.
Completed bodice. Now put this inside the skirt, right sides together and stitch around. Before you do this make sure you have the right waist size because this is not stretchy.
