Monale, I do ruler work on my domestic machine. Generally, there are 2 thicknesses of rulers: 1/4 inch thick for longarm machines and 1/8 inch for domestic machines. I FMQ with rulers on my Pfaff, Elna and Kenmore home machines. I have rulers with various curves and shapes made particularly for ruler work, I have used my rotary cutting rulers for straight lines, old plastic cutting templates (1/8 inch thick of course), had plexiglass cut to shape, and even used used photo matting board. The thing is that you have to make sure that your ruler foot is low enough so that your ruler will not accidentally slip under it and get hit by your needle. There are lots of Youtube videos available on ruler work with a domestic machine for you to learn with. Just make sure that they are not videos for longarm machines. Have fun and use whatever will work for you before investing $$$'s.
