I wrote the reply that PaperPrincess posted and would add this: For the baby quilt with a minky back that I'm currently working on I quilted it with the Janome 6600 dual action foot (walking foot) using just straight lines about 1/8" on either side of my long piecing seams. Then I went back and did minimal FMQ in the blocks - mostly larger flowers - large as in ... 3" across. This still met the 3 - 4" guideline for my batting, but was not too fussy. I'll post a pic when I'm done. I'm working on so many projects right now that I do a little of this and a little of that! I'm also working on a brand new (to me) machine and am feeling my way through.
On my old machine - a little Brother 9000 - I did not use batting so outlined blocks with straight stitches and called it good.
