:-) thanks to all the good advise on my pfaff 1200 when i lst got it. thought i would let everyone know that you all steered me in the right direction. correct size needle, good thread, plenty of oil, tension just so. the one thing that i think that helped the most was no more than l finger width higher than the bed of the sewing machine, as i roll my quilt. all bars completely level. and my DH made sure the frame, and machine shelf was completely level. and as i raise the rolled quilt and raise the bars, I make sure both ends are raised exactly the same, and are level. i have a level handy. so it works like a dream. my lst queen is about half done. with the inspira frame, and phaff 1200. thanks to all you great gals for the wonderful help.
