Don't forget to take a machine needle in your sewing machine testing kit. In my purse, I carry a small spool of thread, sewing machine needles, a scrap of fabric and also s small pair of scissors. This is my 'just in case' kit, just in case I come across a vintage or used machine where ever I go, yard sales, flea markets, Goodwill, etc. This way I'm ready to try any machine I come across. I also have my little camera in my purse too. I don't use the cell phone camera as I prefer the other one instead. Good luck at the sale and let us know what you find there!
