As I mentioned in my post yesterday, I am rather new to sewing and very new to serging. I asked a question about sheers and couple of nice folks replied. One of them responded with some instructions using a flatlock with three threads. I have a basic Singer serger with 4 loopers that I have used some. Is something my macine will do? Do I just need to read my owner’s manual? I hope the person that answered my question yesterday will see this.
