I am a newby and have LOTSA questions. You all seem so knowledgeable. My first question: I have an inexpensive sewing machine with no manual included. Walmart special. So, I don't really know how to work it. What should the tension be so you don't get the ruffles or eyelashes on the opposite side of your work? It took me hours to pick out stitches from a piece last week and don't want to make that mistake again. Thanks.
