When I first got my sewing machine, it sat in the box for over a year. My mother would often ask if I was planning to use it and I would always answer "yes". One day I was finally ready and opened the box and started sewing. It was as simple as that.
My serger looks more complicated than my sewing machine. I read the instruction manual and plan to look at it up on my shelf for a little bit longer. I have a million projects planned so I doubt it will be on the shelf for too long, but for now I am still taking it in. I am fully confident that when I decide to start using it I will be a serging pro.
