KarenfThanks @Karenf!
Here's the Bobbin Compatibility List from Superior Threads:

@Girltwin64, it looks like most Janome machines only use Class 15 bobbins so, unfortunately, these L-style bobbins would not work in your Janome MC 6600 bobbin case. However, many sewers like to use these colorful pre-wound bobbins for applique and hand stitching like how @sarahelizabeth suggests in her poll.
Hope this helps!

Girltwin64I have used them on my Janome MC 6600 and they work fine. I found that I needed to remove the paper edges and have had no problem. I don't know if you're suppose to do this, but I did 😊
