well I'm using a singer ingenuity, pretty plain, I have a real problem keeping a steady speed, just about the time I get it all together and looking good it's time to stop and reposition the quilt. Last nite I unthreaded the needle and held the foot pedal in my hand and squeezed till it got to the exact speed I like and made a mark on it. My hubby super glued a small piece of wood so it will not go any faster than that so now all I have to do is "put the pedal to the metal" ( or wood rather lol) I have learned that faster is better than slower and my stitches are well regulated, they're a little smaller than I'd like but that's better than too big, I'm trying to get my movement down now to make them a tiny bit bigger but the quality is good. I still can't follow lines though, I think that is going to take a lot of practice.
