If you have an embroidery machine, Eileen’s Machine Embroidery suggests using it to make buttonholes on your garment. She cites the better control over length and placement as the number one reason to do this. There’s also the fact that each buttonhole will be the exact same size. She includes a link to download an embroidery file for a standard buttonhole in 2 sizes (1″ and 2″) and 2 shapes (square and round). You can resize the length to get the exact size you need. Go to Eileen’s Machine Embroidery blog for the tutorial and the free buttonhole file.
