I got stippling down pretty quickly and am now working on other types. It took me a bit longer to figure out straight(ish) lines in FMQ. I find my machine does better if I have a regular foot rather than a quilting/darning foot on when trying to do FMQ and straight(ish) lines.
I am still working on my feathers. I can do small ones, but still want to learn to do bigger designs. To me, it's harder to do on a small domestic machine .... maybe if I can get a plexiglass top so that my machine is more level with a larger table top.....
