I bought a suction holder( for I thought a bath tub or shower as a helper) at a thrift store for $2 and i use it on my rulers and it helps. It does not hold for a long time but I just release and put it on the ruler again. My waste was the embroidery module I bought with my Bernina 440 I have not used it. Long story about the lessons and time. I have used my pounce but I have to use a wet/damp wash cloth on the quilt before I use the pounce and then you see the imprint better. This thread has been great!
