I have a Janome 11000. The way I learned to do this
1. change out presser foot for embroidery foot
2. Lower feed dogs
3. tighten bobbin tension
4. speed up your machine
Once you have these done, you should be able to go for it. I'm not good at it, but I'm getting better and I don't do it too often. So it isn't rocket science.
I made practice blocks, sandwiched them, and practiced the free motion stippling and it's pretty easy to get into a rhythm. Actually, now that I'm thinking about it, I should go ahead and bind the edges of these small quilts. The stippling on them looks pretty good.
Good Luck.
