The sewing machine has been revived, and for no more expense than the cost of an annual tune-up! While I definitely should have been oiling throughout the tent project, apparently I didn't push it beyond repair!
I can pick it up this week and will probably do so on Friday, after class and before going over to help with set-up at the Highland Games site. Until I actually get it home and use it a little, I'll still be nervous. This is good news though and I'm excited!
