I just cut about two inches off the top to make them rectangles, serged and hemmed them. I added a bit of ribbon down the sides just for pretties.
My mister loudly protested them, because they require him to eat neatly. That is what I call a double bonus...cheap mats and a tidy table. =)
Oh yes, I took my machine in to the store where I bought it to see if they could figure out why it was giving me fits. As it turns out the little screw on my bobbin just needed to be tightened, and I needed to use better thread. I had no idea that there was any difference in the least between threads! Apparently, Coats and Clark thread has a coating on it that some machines don't like. She put Mettler thread in it and it worked as smooth as ever! So, if your machine randomly starts sounding like a woodpecker and popping needles...try switching out your thread!
