I just began doing FMQ on my new Juki. Luckily, I can say, the results have been wonderful with that machine...but my stitches will need practice!! I just belly laughed about your tongue comment, because I make weird mouth movements while doing it too...lol. I tend to tuck my lips like a toothless woman and back out...I do it so much, that my lips get worn out!! lol
Of course I am doing stippling to begin with, just to get the hang of moving the fabric, but I find myself quilting too densely I think, as my Bow Tuck needs absolutely no batting and is at attention..lol Any suggestions, besides wine?? lol
