I need a used sewing machine, pls how do I get?

I bought one at a antique store. Goodwill has them sometimes.

Jo Ann's does not sell any used machines.

Check at pawnshops Thrift stores

Try offer up

Try googling sewing machine shops in your area. I am sure they have used refurbished machines.

Just walk in and ask the ladies at the cutting counter when they are between customers. I know Joann keeps a variety of machines for various purposes, and the cutting counter ladies are knowledgeable about the machines since they talk with people who use them a lot and most of them sew themselves
