Finally decided to buy the Grace Sure Stitchregulator.
I have had my Janome 1600p qc machine on gracie 2 frame now for a month and still can't keep all my stitches the same so i finally broke down and ordered the Grace Sure Stitch Regulator. I sure hope I want be sorry for spending all that money, They assured me it would work on my frame. My husband wanted me to go ahead and get the carriage upgrade but I decided to wait and see how this works before i spend any more money. I have been trying to do a panograph and everytime i slow down it makes long stitches and go faster they are too small. I know it takes practice but my patience was getting very slim. Sure hope this solves my problem.
