Go to the Pfaff website and locate a machine dealer near you. ( if you dont know where Mom bought the machine) Ask them to help you with getting started with your moms' machine. You will then have an opportinuty to ask questions and gain tips about the machine. Pethaps if you explain the circumstances of how you acguired the manine..they may not charge a fee for a lesson. Assuming that they might charge a fee. And yes, You Tube videos can be helpful too. Have fun and welcome to the wonderful world and sisterhood of sewists!
