I don't know where it's coming from, but I have been very productive this Christmas season. I decided Nolan needed a vest to go with Savannah's Christmas skirt. I found a wonderful pattern here, it includes full size pattern for sizes 12 month-10? I can't remember what it goes up to. They were supposed to wear their outfits to church today but Savannah has a fever so she couldn't go.
Ok, so the pattern was very simple and of course I changed it slightly. Here is what I did:
It was not meant to be reversible but was easily done. Skip the welt pockets, instead of folding the hem to the inside stop all bottom seams 1/2" from bottom, when you go to do the hem just fold up the bottom of the lining 1/2" and press, do the same with the outer vest then pin together and topstitch around the whole bottom to enclose the hem. Do your buttons and button holes normally, then put buttons on the other side of the buttons you already have, I would use flat buttons for more comfort while wearing.
Just a few more must do changes, make sure you clip all curves before turning right side out otherwise it won't lay flat, and topstitch around entire vest at 1/8" including arm holes. This helps it lay flat and adds a really nice look.
The sizing was perfect.
