I thought this was a real person from the thumbnail too! I was confused for a few seconds when I opened your post... my brain needed time to catch up to my eyes and realized it was sculpted lol. You are extremely talented!
Hmm so over the weekend I found out that my mom still had my great grandma's sewing machine in the basement at my parent's lake house. Since it has been sitting there for years, she didn't mind that I took it home with me! And it happens to look exactly like yours... what letters does your serial number start with? I have the manual for mine and could let you know how to thread it and wind the bobbin if you aren't able to find a free one.
Wow I can't believe you did that so quickly! It looks really great! You've inspired me to try to get myself to do something like this... even though in reality I'll probably just keep staring at all the yarn I have laying around haha
