I use pantographs almost always when I quilt. My best quilting buddy and I bought an APQS Lenni in October 2016 and we have quilted more than 350 quilts. As our quilts will be used and washed frequently, we don't like really dense pantos as that makes the quilt stiff and flat and not as cuddly. We also do not want to spend hours quilting very intense design as many of our quilts end up at the Youth Shelter and don't need that much quilting. I like to zip down a row and like continuous flowing or curved designs while my buddy likes a few points in the design which she can use as a resting spot. I don't like designs featuring perfect circles or lots of straight lines as they are hard to do when you have a hand guided machine.
