Then you take the bobbin and slide Singer 3116 Simple Sewing Machine in to the center post. It sits in a half moon shaped depression that you slide a ' hook ' into and then while holding that easily disgorged piece with one hand you have to slide the race over all that and then clip ' dog ears ' over each side to hold it in place. The bobbin jammed over and over and over the first day I started to use it.
I would be embarassed to put my name on anything that hookie. Do not waste your time or your hard earned money.
The reason I gave the Singer 3116 Simple Sewing Machine a one star was because there is no zero star.
