The throat plate that comes with the Bernina (and on most multi-stitch machines) is a versatile one which will accommodate a zigzag or decorative stitch as well as a straight stitch.
Having been "raised" on a machine where I always switched plates, I can see the benefits of having the tiny hole for the needle to pass through. It makes perfect stitches even more... perfecter. (Those who know me will understand how I cringed when I wrote that, having been an English teacher in a past career *-) If you scroll back up to the top picture, you will see it comes with a bright orange warning to help you remember to change the plate when you are changing your stitch width. Otherwise, good bye needle.
I used the plate to start the free motion quilting on my spring quilt. I can't show you the front of the quilt yet, but here's the back. Can you tell what motif I am quilting? Only 32 more of these to do before moving on to the next section. So far, so good.
