I kind of like how they look, as well as how utilitarian they are. I've been trying to figure out a way to make one that won't get in the way of the light on my Featherweight, will have some sort of thick back on it (like the flexible plastic on those semi-disposable cutting boards) to protect the machine and will actually have a little fluff in it so the pins can go straight in, but stop at the protective backing.
We'll see what I can come up with.
