I am not new to sewing in the least. I have the Lovley Lilac machine. I am having trouble threading the machine. I did get it to thread once and was able to get one side of my project stitched up (slip covers nothing crazy). I went to thread it again to continue and no soap. when I turn the handwheel to have the thread pull through it seems to be getting caught where my bobbin is. Am I doing something wrong that I don't realize I am doing. Help pls!!!!
