Whew.

The sewing machine is working, so far. It worked well enough to finish the last tab for the doublet.

And I think the instructions in the sewing machine manual are wrong, as when I load the bobbin the way they say to do it, it snarls beyond comprehension. When I load it the way I have been doing it for the last eight years, it works (now that I have cleaned the lint from the bobbin area...).

Time will tell if this will work correctly...
