As a sewist, I am generally sewing not only quilts , but also apparel. I love that I can work with different types of fabrics and the colors available are an endless array. Recently, my daughter brought her serger and wanted to use in her sewing, A quick guide on You Tube had both of us following instructions to thread this machine. I still cannot figure why 4 threads! No matter, we reached the point where all threads were threaded and ready to sew. So sew we did! It was a great relief to see this small machine doing what it does. So many thsnks to You Tube! Really a great guide with step bt step instructions!
