After years of being too "chicken" to try using invisable in the bobbin and the top , I did it ..... the other posts are right on point about slowly winding the bobbin.
I use a smaller needle and have been using invisable thread in top and bobbin now for a few years. Do buy the good stuff when it comes to the invisable thread, there are enough issues with invisable , than to have to deal with a thread that no matter what just will not work properly. I tossed all my cheap stuff I got at JoAnn's ... wish I had back all the time wasted trying to get it to work, and restore the gray hair(s) I got in the process as well.
