I don't have a Janome but I Googled the set to see it. It looks like it only does single fold binding. Like bias tape. Personally, I would only bind a mini or maybe a wallhanging with single fold binding. I just don't think single fold will hold up to alot of the use that well-loved quilts get.
This is the link that I looked at:

I used to hate binding too. And I was terrible at it. But I used somne of Sharon Schambers techniques and a few others and now I actually kind of enjoy it and they look much better. I would keep practicing. It will come.
