|Have you ever tried making a buttonhole when the button would not easily fit into your buttonhole attachment because of shape or thickness? Do what I do. I keep forty-one cents, a quarter, a nickel, a dime and a penny on my sewing table. When it's time to make a buttonhole I grab the coin that is closest in size to the button and insert it into the buttonhole attachment. The coins are flat and fit perfectly. I've been doing it for years without any mishaps.
