I have no idea how sergers work, or I would offer advice, but know that you have my commiseration. Rethreading the machine usually fixes it on my sewing machine, but thats a whole different animal.
We got the bricks, the flagstones, and I got some scrap wood to make little planters for DD. We also watched her ice skate(at 20 months!!!) and went out to dinner with the in-laws, which they very sweetly paid for.
Made kombucha, made the bed, planned garden beds better (easier when you know what your materials are!), did laundry, watered seedlings, and planned a family date night with one of my husband's coworkers, whose daughter is a month or so older than ours.
Dishes put away, wiring, cardboard recycling (three week old chore DH has put off), and the trash out have NOT been done. Strange how those are all DH's chores.
But I am psyched about how much I got done, especially the big moving projects, since I needed DH/the borrowed car, which I can't do myself with DD.
