This is how I thread my Bernina 950. This is a pic of mine, I added a thread stand after I bought it.
This is a view from the back. Right now the machine is threaded from the thread stand. If using cone thread and a thread stand, first the thread goes through the top of the stand, then the hook behind the thread post, then the hook behind the take up lever. If you are using a spool on the thread post, the only hook you use is the one behind the take up lever.
Another closer view of the hook behind the take up lever. And showing the thread going into the guide toward the front of the machine.
The thread comes from the back on the right through the guide. Down and under the thread regulator, up through the take up lever, and down through the thread guide just above the needle, then through the needle.
Hard to see, but it is important to note that the needle is inserted slightly off center. The eye should be facing between the 6 and 7 on a clock. The long groove is the front of the needle. Organ 16X231 BALL POINT Needles and Organ 16X231 SHARP Needles .
This is how the bobbin goes in the bobbin case. The thread rolls off over in the direction you see the thread going.
Another look. Bobbin in case. Sorry its a little fuzzy, you get the idea...
I hate winding bobbins in the middle of a project (thought you can with the Bernina 950)or unwinding bobbins for a new thread color. I bought 20 extra Bobbins as soon as I could find them.
