Hi Katrine
I was admiring your pin cushions at cat-on-a-mac's Gallery.
Decided to come to your site to see pictures of your quilts (all lovely) and stumbled across this question
I am a fanatic Bottom Line user - piecing hand and machine., hand applique, quilting hand and machine.
My Bernina will take it top and bobbin - I use an 80/12 sharp or topstitch
Neither of my Jems - Gold or Platinum will take it on top, only the bobbin.
