I have no advice about which pounce pad to use but I have a question relating to them.
Do you think that in time the fine particles of chalk would damage the machine. The reason that I ask is that when I first started quilting I used regular chalk to draw lines and sew on them and not long after that I started having quite a few problems with my machine - to the point that I had to buy a new one. So I have my reservations about using the pounce pads. Maybe it had nothing to do with the problems but I will always have my doubts.
Has anyone else had similar problems or thoughts. I would be very interested to hear. Thanks
