Tartan,rulers are great! lines are impossible for me without them..our Joann store carries them (Thick,Dretz)and I also have another tool that has a curve and some straight edges, I really like to FMQ my own designs in nice curvers...Sitka rose and leafs and vines, leaves and grapes.. still working on feather fills..etc. I don't know how I would do them on a reg. sewing machine! Every things seems backwards to me on a reg.machine
