I have been on a "get it finished" kick since I retired. Everyone of my quilts has a Panto design except my son's wedding quilt. I love those designs and they are exactly what my quilts needed. I do a lot of family quilts which get lots of use, QOV quilts and Community Quilts. None of these need custom quilting. There is nothing wrong about quilting with pantographs. Do what suits you, your abilities and your time. Quilt on!
