I worked on the first couple of projects all sort of at the same time, but I think the first finished one was my plaid 1880s bustle dress, and the trimmed bonnet to match:

This hardly counts, but I made a new stomacher for my 18th c court gown:
Not sewing, but costume-related: I built a large walk-in closet in my garage! I honestly can't remember how I was fitting things in before I made this closet. And apparently I never posted pics of it to instagram, so the only pic to share comes from this post: theladyrebecca.dreamwidth.org/294624.htm
Star Wars flight suit commission. I don't think I have pics of that.

Commission of alterations for the Silverbells carolers, which luckily turned out to be much easier/less than I had feared.

www.instagram.com/p/B6ZwfacAwWk/ - Pelerine/fixing the sleeves on my 1840s dress
A Star Wars bow tie for my dad for Christmas (which I guess I didn't share a pic of)
I know looking at that as a list, it seems long, but a fair amount of it is either commissions, very small projects like modern skirts, or alterations/accessories to projects. I'd love to have more actual full historical projects this year, but that is for another post.
